Introduction
This European Standard for copper alloy ingots, and copper and copper alloy castings is based on previous
national standards and harmonizes the compositions and mechanical properties required.
This standard does not include copper refinery shapes which are intended for working into wrought products
and are the subject of EN 1976. Neither does it include master alloys intended for the manufacture of copper
alloys which are the subject of EN 1981.
The essential information relevant to correct ordering, given in Clause 5 of the standard, is supplemented by
Annex A, which is based upon the recommended practice for the ordering and supply of castings given in
EN 1559-1. Its purpose is to assist the purchaser in providing full information to the supplier to ensure that he
supplies castings to the purchaser's intended requirements. It is recommended that full consultation takes
place between the purchaser and the supplier at the stages of enquiry and ordering.
Sampling and testing rates, where applicable, are specified in Clause 7. For certain applications, more
rigorous inspection procedures may be required. Annex B gives a range of supplementary inspection
procedures which may be invoked, at the option of the purchaser [see 5 p)].
1 Scope
This European Standard specifies the composition, mechanical properties and other relevant characteristics of
the materials. The sampling procedures and test methods for the verification of conformity to the requirements
of this standard are also specified.
This standard is applicable to:
a) copper alloy ingots intended to be remelted for the production of castings; and
b) copper and copper alloy castings which are intended for use without subsequent working other than
machining. The castings may be manufactured by the sand, permanent mould, centrifugal, continuous or
pressure die casting process.
Recommended practice for the ordering and supply of castings is included in Annex A. Optional
supplementary inspection procedures for ingots and castings are included in Annex B.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
cast
any of the following:
a) product of one furnace melt; or
b) product of one crucible melt; or
c) product of a number of furnace or crucible melts where these are aggregated and mixed prior to
sampling; or
d) production corresponding to the intervals between additions to a holding furnace of new furnace or
crucible melts (for example in permanent mould casting or pressure die casting); or
e) product from a number of consecutive melts of the same alloy through a die, in the case of continuous
casting.
3.2
batch
any of the following:
a) number of ingots taken from a single cast; or
b) number of castings of the same design produced from a single cast; or

4 Designations
4.1 Material
4.1.1 General
The material is designated either by symbol or number (see Tables 1 to 40).
4.1.2 Symbol
The material symbol designation is based on the designation system given in ISO 1190-1. A suffix -B is added
to the designation to identify material in the form of ingots and a suffix -C is added to the designation to
identify material in the form of castings (for example CuSn5Zn5Pb5-C). These suffixes also serve to avoid
confusion with wrought products of a similar alloy.
NOTE Although material symbol designations used in this standard might be the same as those in other standards
using the designation system given in ISO 1190-1, the detailed composition requirements are not necessarily the same.
4.1.3 Number
The material number designation is in accordance with the system given in EN 1412 (for example
CuSn5Zn5Pb5-C is CC491K).
4.2 Casting process
The designations used to indicate the casting processes referred to in this standard are based on those given
in ISO 1190-1, as follows:
GS sand casting;
GM permanent mould casting;
GZ centrifugal casting;
GC continuous casting;
GP pressure die casting.
4.3 Product
The product designation provides a standardized pattern of designation from which a rapid and unequivocal
description of a product is conveyed in communication. It provides mutual comprehension at the international
level with regard to products which meet the requirements of the relevant European Standard.
The product designation is no substitute for the full content of the standard.
The product designation for products to this standard shall consist of:
 denomination (Ingot or Casting);
 number of this European Standard (EN 1982);
 material designation, either symbol or number (see Tables 1 to 40);

6 Requirements
6.1 Composition
The composition of ingots and castings shall conform to the requirements for the appropriate material given in
Tables 1 to 40. The analysis shall be carried out in accordance with 8.1. In the case of ingot casts of more
than 2 t, both samples selected in accordance with 7.2.2 b) shall conform to the composition requirements.
NOTE 1 In Tables 3 to 40, elements with known harmful effects are shown separately, below the line, from alloying
elements. Maximum limits for these harmful elements are specified.
NOTE 2 Small amounts of residual elements other than those listed in the composition Tables 3 to 40, for example As,
Bi, Cd, Co, Cr, Mg, Ti, may be present in amounts which generally have no deleterious effects. If requested at the time of
placing the order, the analytical determination of any of these elements, or of any other residual element not included in
the composition tables, together with limiting values, should be agreed between the purchaser and the supplier. Usually
such elements (excluding oxygen) will not exceed 0,05 % individually in ingots or 0,06 % in castings, and the total of such
elements will not usually exceed 0,20 % in ingots or 0,25 % in castings.
NOTE 3 In all tables of composition the "Remainder" is the balance between the sum of the elements determined and
100 %. It is not determined by analysis.
6.2 Mechanical properties
The mechanical properties of castings shall conform to all the requirements relevant to the material and
casting process given in Tables 1 to 40. The test(s) shall be carried out in accordance with 8.2.
NOTE 1 No mechanical properties are specified for ingots.
NOTE 2 The mechanical properties specified in this standard relate to separately cast test bars unless otherwise stated.
Separately cast test bars have a valuable function as a check on the quality of the material and also on the foundry
technology. It is emphasized that the mechanical properties obtained when testing a casting may differ from those
obtained from a separately cast test bar(s) because of possible differences in structure between the test bars and the
castings, arising mainly from variations in section thickness.
NOTE 3 All the mechanical properties given for castings in Tables 1 to 40 are mandatory requirements (but see note 4).
However, only those mechanical properties printed in bold typeface are normally determined on a routine basis.
Determination of the other properties should be specifically requested, if required [see 5 o)].
NOTE 4 Because of the dependence of the properties of pressure die castings on the injection parameters, the
mechanical properties given in Tables 4, 5, 7, 8, 10 and 12 are given for information only.
6.3 Electrical properties
The electrical conductivity of Cu-C (CC040A) castings shall conform to the requirements given in Table 1. The
electrical conductivity of CuCr1-C (CC140C) castings shall conform to the requirements given in Table 2. The
test shall be carried out in accordance with 8.3.
NOTE 0,58 MS/m is equivalent to 1 % IACS.
6.4 Microstructure and grain size
For marine and other applications requiring high resistance to corrosion, the microstructure of
CuZn35Mn2Al1Fe1-C (CC765S) castings shall reveal a minimum of 15 % alpha-phase when tested and
examined as described in 8.4.1 [see 5 k)].
Ingots in certain alloys shall have maximum average grain diameters, as follows:
 0,150 mm for material CuZn35Pb2Al-B (CB752S) (see Table 5) and CuZn39Pb1Al-B (CB754S) (see
Table 7), when specifically ordered in the grain refined condition [see 5 i)];
 0,100 mm for material CuZn39Pb1AlB-B (CB755S) (see Table 8);
 0,300 mm for material CuZn37Pb2Ni1AlFe-B (CB753S) (see Table 6).
The tests shall be carried out in accordance with 8.4.2.
6.5 Dezincification resistance
The depth of dezincification after the test, in any section of a casting in CuZn33Pb2Si-C (CC751S) and
CuZn35Pb2Al-C (CC752S) (see Tables 4 and 5), produced by permanent mould or pressure die casting, shall
be:
 for Grade A: maximum 200 µm;
 for Grade B: mean not to exceed 200 µm and maximum 400 µm.
The test shall be carried out in accordance with 8.5.
6.6 Freedom from defects
6.6.1 Ingots
Ingots shall be free from dirt, dross, slag and residual moisture.
6.6.2 Castings
The castings shall be supplied fettled unless otherwise agreed between the purchaser and the supplier at the
time of ordering [see 5 p)]. Gates and feeders shall be removed and residues of moulds shall be removed
from accessible surfaces.
7 Sampling and testing rates
7.1 General
Except where a foundry operates a certified quality system conforming to EN ISO 9001, and as a
consequence a different sampling regime has been agreed, the minimum sampling and testing rates for
verifying conformity to the requirements of this standard for composition, mechanical properties,
microstructure and dezincification resistance shall be as given in 7.2 to 7.5. The procedures for retesting in the
event of a test piece failing the analysis, mechanical properties test or dezincification resistance test shall be
as given in 8.7.
7.2 Analysis
7.2.1 General
Samples shall be taken from the melt they represent and poured into a clean chill mould, which is designed to
give analysis samples of a shape and size appropriate to the analytical technique to be employed.
7.2.2 Ingots
Samples shall be taken from the melt to represent each cast, as follows:
a) for casts of 2 t or less, one sample shall be taken;
b) for casts of more than 2 t, two samples shall be taken, one at the beginning of the cast and one at the end
of the cast.
7.2.3 Castings
7.2.3.1 Casting from a holding furnace
Samples shall be taken from the holding furnace at a rate of one per cast [see definition of cast in 3.1 d)].
7.2.3.2 Continuous casting
Samples shall be taken during the run of a cast [see 3.1 e)] at a rate corresponding to the pouring of each new
melt.
7.2.3.3 Non-continuous casting
When the furnace charge consists wholly of:
a) ingots for which an analysis is already available; and/or
b) properly segregated and identified foundry returns,
then the rate of sampling shall be left to the discretion of the founder.
For other furnace charge constituents, samples shall be taken from the melt to represent each cast.
7.3 Mechanical tests
7.3.1 Mechanical testing of ingots
No minimum inspection requirements for the testing of ingots for mechanical properties are specified.
NOTE A purchaser may specify tensile testing of ingots as an optional requirement (see B.3.1).
7.3.2 Mechanical testing of continuous castings
When mechanical properties are specified, the minimum sampling and testing rate shall be one sample for
each 5 t of product of identical dimensions and composition, except that for hardness testing of castings in
CuCr1-C (CC140C), the minimum rate shall be one test per cast, or per heat treatment batch, whichever is the
smaller mass.
7.3.3 Mechanical testing of non-continuous castings
The minimum sampling and testing rate for non-continuous castings shall be:
a) for castings in alloys CuZn35Mn2Al1Fe1-C (CC765S), CuZn34Mn3Al2Fe1-C (CC764S),
CuZn25Al5Mn4Fe3-C (CC762S), CuAl10Fe2-C (CC331G), CuAl10Ni3Fe2-C (CC332G),

or 3.1 c)], or one test per 1 t of fettled castings, whichever is the less frequent rate of testing;
b) for castings in all other alloys for which routinely determined mechanical properties are required, at a rate
corresponding to one test per 5 t of fettled castings;
c) for castings in alloy CuCr1-C (CC140C), the minimum sampling rate for hardness testing shall be one test
per cast, or per heat treatment batch, whichever is the smaller mass.
7.4 Microstructure
7.4.1 Alpha-phase content
The sampling rate for the determination of the alpha-phase content of castings in alloy CuZn35Mn2Al1Fe1-C
(CC765S), shall be one sampling unit per cast.
NOTE The determination may be conveniently carried out on the end of a tensile test piece.
7.4.2 Assessment of grain refinement
When grain refinement of ingots is specified [see 6.4 and 5 i)], the sampling rate shall be one ingot per cast,
taken midway through the cast.
7.5 Dezincification resistance
For castings in alloys CuZn33Pb2Si-C (CC751S) and CuZn35Pb2Al-C (CC752S), one sample casting shall be
taken from each batch [see 3.2 b)]. Where castings are required to be heat treated, the sample casting repre-
sentative of each batch shall be taken after heat treatment. Of the sampling units representing batches of the
same design of casting, a minimum of one in ten shall be selected for testing.
Two test pieces shall be taken from each casting so selected, one from the thickest section of the casting and
one from the thinnest section. The test pieces shall be taken in such a way that the properties of the material
are not affected.
Sampling units that have been taken but not tested shall be kept until the next in sequence has been tested
and found to be satisfactory. If this next sampling unit proves to be unsatisfactory, then intermediate sampling
units shall each be tested to verify the conformity of each design of casting in the batches represented.
8 Test methods
8.1 Analysis
When analysis is carried out to verify conformity of a batch of ingots or castings with this standard (see 6.1
and 7.2), except in cases of dispute, the analytical methods used shall be at the discretion of the supplier. The
supplier shall ensure that the precision of the analytical methods used is compatible with the number of figures
for the composition limits given in Tables 2 to 40. For expression of results, the rounding rules given in 8.8
shall be used.
NOTE In cases of dispute concerning the composition of ingots or of castings, the method of sampling and the
analytical procedure to be used should be agreed between the disputing parties.
8.2 Mechanical tests
8.2.1 Tensile test
When the tensile properties are determined to verify conformity of a batch of ingots or castings with this
standard (see 6.2), the test shall be carried out in accordance with EN 10002-1 on the proportional test pieces
prepared from the test samples or bars (see 8.2.2).
For expression of the results of the tensile test, the rounding rules given in 8.8 shall be used.
8.2.2 Preparation of tensile test samples
Sand cast test bars shall have diameters between 12 mm and 25 mm. They shall be cast separately from the
castings in sand moulds, from the same cast as the castings they represent.
NOTE 1 For alloys with a long freezing range, a test bar fed at one or both ends is recommended. For other alloys, a
test bar fed all along its length is preferred.
In the case of permanent mould castings, test bars shall be separately cast in metal moulds.
NOTE 2 The test bars, whether sand cast or permanent mould cast, may be tested as cast (i.e. without machining).
Alternatively, at the discretion of the supplier, test pieces may be machined from the bars for testing.
If test bars representing sand or permanent mould castings are machined, they shall have an effective diameter between
10 mm and 18 mm and shall be proportional test pieces, as described in EN 10002-1.
For centrifugal castings, the test bars shall be taken either from the casting, or cast separately, as specified by the
purchaser [see 5 m)]. Separately cast test bars shall be cast in moulds comparable to the moulds for the castings. If the
purchaser opts for test samples to be taken from castings over 50 mm thick, the location of the test sample and its
properties should be agreed between the purchaser and the supplier.
NOTE 3 For castings which are to be heat treated, for example for homogenizing or stress relieving, the test bars
corresponding to the castings should be heat treated with the castings, unless otherwise agreed between the purchaser
and the supplier.
If test bars are required for pressure die castings, a separately cast flat test bar shall be used and tested without
machining. It shall be from 2 mm to 4 mm thick and its freezing rate and injection parameters shall be as comparable as
possible to the die castings represented. (See note 4 of 6.2 concerning the mechanical properties of pressure die
castings.)
For continuous casting, test bars shall be taken from the casting itself, with a gauge length parallel to the direction of
casting.
NOTE 4 If the shape or dimensions of the continuous casting precludes the use of a standard proportional test piece,
then the form of the test piece and the results to be achieved should be agreed between the manufacturer and the
purchaser.
NOTE 5 For continuous cast bars with diameter greater than 300 mm, the tensile test piece may be machined from a
transverse slice of the casting.
NOTE 6 The mechanical property requirements given for continuous castings apply to sizes up to and including
300 mm external diameter. For larger continuous castings, the mechanical property requirements should be agreed
between the supplier and the purchaser.
8.2.3 Hardness test
Where practicable, hardness tests shall be made either on a convenient portion of the casting, unless
otherwise specified, or on the end of the tensile test bar representative of the castings. The test shall be
carried out in accordance with EN ISO 6506-1 using a 0,102 F/D ratio of 10, e.g. using a 1,00 mm diameter
ball and a force of 98,07 N, or a 2,5 mm diameter ball and a force of 612,9 N.
8.3 Electrical conductivity
When the electrical conductivity of Cu-C (CC040A) and CuCr1-C (CC140C) castings is to be determined, the
test shall be carried out by the use of an eddy current testing instrument.
NOTE The electrical conductivity of Cu-C (CC040A) and CuCr1-C (CC140C) castings is not routinely determined. If
such tests are required, the details of the test and the sampling rate should be agreed between the purchaser and the
supplier [see 5 g)].
8.4 Microstructure
8.4.1 Alpha-phase determination
When the proportion of alpha-phase in the microstructure of CuZn35Mn2Al1Fe1-C (CC765S) castings is to be
determined, a suitable section of the test casting shall be polished, using normal metallographic techniques,
etched to reveal the microstructure and examined microscopically. The proportion of alpha-phase in the
microstructure shall be measured by any appropriate counting method. The test shall consist of at least five
counts and the average of the counts shall be taken as the alpha-phase content of the material.
8.4.2 Grain size determination
The average grain diameter shall be determined in accordance with EN ISO 2624, using either the
comparison method or the intercept method. A transverse slice shall be taken from the ingot, selected as a
representative of the cast, at a point one third of the length of the ingot distant from one end. A surface area
approximately 1 cm on the vertical axis of this slice and one third of the depth of the ingot from the bottom,
shall be prepared for metallographic examination, appropriate for the determination of the average grain size.
8.5 Dezincification resistance
When the dezincification resistance of permanent mould castings, or pressure die castings, in alloys
CuZn33Pb2Si-C (CC751S) and CuZn35Pb2Al-C (CC752S) is to be determined, the test method given in
EN ISO 6509 shall be used on test pieces prepared from samples obtained in accordance with 7.5.
8.6 Surface condition
When there is a special requirement for surface roughness, it is recommended that inspection is carried out in
accordance with EN 1370.
8.7 Retests
8.7.1 General
Retests for analysis, mechanical properties and for dezincification resistance shall be permitted as specified in
8.7.2 to 8.7.4.
8.7.2 Analysis
If an analysis sample gives results which do not conform to the appropriate requirements, a further portion of
the same sample shall be permitted to be taken for check analysis. If this check analysis is found to conform
to the requirements, the ingots or castings represented shall be deemed to conform to the analytical
requirements of this standard. If the check analysis does not conform to the requirements, the ingots or
castings represented shall be deemed not to conform to this standard.
8.7.3 Mechanical test
If a test piece fails a mechanical test, two further samples taken at the same time and from the same cast
shall be permitted to be retested. If the test pieces from both these samples pass the test, the castings
represented shall be deemed to conform to the mechanical property requirements of this standard. If either of
these test pieces fails the test, the castings represented shall be deemed not to conform to this standard.
If any test piece shows evidence of defective machining, or reveals casting defects, it may be discarded and
replaced by another test piece from the same cast.
8.7.4 Dezincification resistance test
If a test piece fails the dezincification resistance test, two further castings of the same type, from the cast or
heat treatment batch, shall be permitted to be selected for retesting.
If the test pieces from both these castings pass the test, the castings represented shall be deemed to conform
to the dezincification resistance requirements of this standard. If either of these test pieces fails the test, the
castings represented shall be deemed not to conform to this standard.
NOTE If a batch of castings fails the dezincification resistance test when tested or retested, the supplier has the
option to heat treat, or to further heat treat, the whole batch and to resubmit it for all the tests called for on the order,
except for analysis.
8.8 Rounding of results
For the purpose of determining conformity to the limits specified in this standard, an observed or a calculated
value obtained from a test shall be rounded in accordance with the following procedure, which is based upon
the guidance given in Annex B of ISO 31-0:1992. It shall be rounded in one step to the same number of
figures used to express the specified limit in this standard, except that for tensile strength and proof strength
the rounding interval shall be 10 N/mm and elongation shall be rounded to the nearest 0,5 %.
The following rules shall be used for rounding:
a) if the figure immediately after the last figure to be retained is less than 5, the last figure to be retained
shall be kept unchanged;
b) if the figure immediately after the last figure to be retained is equal to or greater than 5, the last figure to
be retained shall be increased by one.
9 Declaration of conformity and inspection documentation
9.1 Declaration of conformity
For castings, when requested by the purchaser [see 5 q)] and agreed with the supplier, the supplier shall
issue for the castings the appropriate declaration of conformity in accordance with EN 1655.
9.2 Inspection documentation
9.2.1 For ingots, the supplier shall provide a certificate giving the analysis of each batch of ingots making up
a consignment and, where appropriate, indicating conformity to the grain size requirements.
9.2.2 For castings, when requested by the purchaser [see 5 r)] and agreed with the supplier, the supplier
shall issue for the castings the appropriate inspection document in accordance with EN 10204.
NOTE When ordering products for pressure equipment applications, the equipment manufacturer has the obligation
to request appropriate inspection documentation according to EN 10204:2004, Annex ZA.
10 Marking, labelling, packaging
10.1 Ingots
Each batch of ingots shall be assembled into bundles and each bundle shall be labelled with the
manufacturer's mark, material designation and cast numbers.
10.2 Castings
Castings inspected to optional supplementary inspection procedures specified by the purchaser (see
Annex B), shall be individually marked, or batched and identified by a suitable means as soon as possible
after casting. The identification shall be maintained to enable the castings to be correlated with their relevant
inspection records at the time of their despatch from the foundry.
The form of packaging, if any, for the transport or storage of castings is at the discretion of the manufacturer,
unless a specific agreement has been made at the time of placing the order.
