European foreword
This document (EN 1753:2019) has been prepared by Technical Committee CEN/TC 190 “Foundry
technology”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by March 2020, and conflicting national standards shall
be withdrawn at the latest by March 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1753:1997.
Within its programme of work, Technical Committee CEN/TC 190 requested CEN/TC 190/WG 9 “Cast
magnesium” to revise:
EN 1753:1997, Magnesium and magnesium alloys — Magnesium alloy ingots and castings
Annex D provides details of significant technical changes between this European Standard and the
previous edition.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
Introduction
This document classifies cast magnesium alloys into a number of grades suitable for the applications for
which they might be used.
Sixteen new grades as specified in National [1] [2] [3] or International Standards [4] have been added.
In this standard a new designation system by number, as established in EN 1754 [5], is given.
NOTE This designation system by number is based on the structure and rules of EN 10027-2 [6] and so
corresponds with the European numbering system for steel and other materials.
1 Scope
This document specifies the grades and the corresponding requirements for cast alloyed magnesium
materials.
This document specifies two groups of cast magnesium alloy grades by a classification based on the
chemical composition. The first group deals with grades for magnesium alloy ingots. The second group
deals with grades for magnesium alloy castings.
This document also specifies mechanical properties measured on test pieces machined from cast
samples.
This document does not cover technical delivery conditions for magnesium alloy castings (see
EN 1559-1 [7] and EN 1559-5 [8]).

4 Designation
4.1 Material
The material shall be designated either by symbol or by number as given in Tables 1, 2, 3, 4 or 5.
NOTE 1 The material symbol and number designations are in accordance with EN 1754 [5].
NOTE 2 The comparison of EN 1753 grade designations with the designations from the ISO standard for
magnesium alloy ingots and castings, ISO 16220 [4], is given in Annex A, Table A.1 and Table A.2.
NOTE 3 The materials for aerospace applications referred to in European Standards prepared by ASD-STAN
(AeroSpace and Defence Industries Association of Europe - Standardization) have different designations.
4.2 Casting process
The following symbols shall be used for the designation of the different casting processes:
— S sand casting;
— K permanent mould casting;
— D pressure die casting;
— L investment casting.
NOTE Examples of the use of these designations are given in EN 1559-5 [8].
4.3 Temper
The following symbols for temper designation shall be used:
— F as cast;
— T4 solution heat-treated and naturally aged;
— T5 as cast and artificially aged;
— T6 solution heat-treated and artificially aged.
NOTE Examples of the use of these designations are given in EN 1559-5 [8].
5 Order information
The following information shall be supplied by the purchaser:
a) the number of this document;
b) the designation of the material;
c) any special requirements.
All requirements shall be agreed between the manufacturer and the purchaser by the time of
acceptance of the order, e.g. technical delivery conditions according to EN 1559-1 [7] and
EN 1559-5 [8].
6 Manufacture
The method of producing magnesium alloy ingots and castings shall be left to the discretion of the
manufacturer who shall ensure that the requirements of this document are met for the material grade
specified in the order.
All agreements between the manufacturer and the purchaser shall be made by the time of the
acceptance of the order.
7 Requirements
7.1 Chemical composition
The chemical composition of magnesium alloy ingots shall conform to the requirements for the
appropriate material grade given in Table 1.
The chemical composition of magnesium alloy castings shall conform to the requirements for the
appropriate material grade given in Table 2.
If not otherwise specified in the enquiry and order, the chemical composition of the ingot or casting
shall relate to that of the cast samples taken from the melt at the time of pouring.
NOTE 1 For additional information regarding the manganese and iron contents, see Annex B.
NOTE 2 For additional information regarding the maximum content of alloying and trace elements in ingots
and castings, see Annex C.
7.2 Tensile properties of castings
7.2.1 Test pieces machined from cast samples or as cast test pieces
The mechanical properties obtained from test pieces prepared from cast samples for sand castings and
permanent mould castings shall meet the requirements given in Tables 3 and 4. As appropriate, the
tests shall be carried out in accordance with Clause 9.
NOTE 1 Mechanical properties obtained from test pieces prepared from cast samples for investment castings
are not specified as experience is limited. As a general rule they are similar to those for permanent mould castings.
NOTE 2 The mechanical properties obtained from test pieces prepared from separately cast samples for
pressure die castings are very dependent upon injection parameters. Therefore, the properties given in Table 5
are for guidance only.
NOTE 3 Tensile testing requires sound test pieces in order to guarantee pure uni-axial stress during the test.
7.2.2 Test pieces machined from samples cut from a casting
If applicable, the manufacturer and the purchaser shall agree on:
— the location(s) on a casting where the sample(s) shall be taken;
— the mechanical properties that shall be determined;
— the minimum values, or allowable range of values, for these mechanical properties (for information,
see Table 3 and 4, NOTE 1).
NOTE 1 The properties of castings may not be uniform, depending on the complexity of the castings and
variation in their section thickness.
NOTE 2 Mechanical properties for test pieces cut from a casting are affected not only by material properties
(subject of this standard) but also by the local casting soundness (not subject of this standard).
7.3 Hardness of castings
Guidance values for Brinell hardness of castings are given in Tables 3, 4 and 5.
The Brinell hardness test shall be carried out on porosity free areas of castings or on a test piece which
has not been stressed.
7.4 General condition of the product
The product shall have a clean surface in accordance with an agreement between the manufacturer and
the purchaser, and shall be free from visible and internal imperfections to a level also agreed between
the manufacturer and the purchaser (see EN 1559-5 [8]).
