Foreword
This document (EN 573-3:2009) has been prepared by Technical Committee CEN/TC 132 “Aluminium and
aluminium alloys”, the secretariat of which is held by AFNOR.
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text or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn at
the latest by October 2009.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
CEN/TC 132 affirms its policy that if a patentee refuses to grant licenses on standardised products under
reasonable and not discriminatory conditions, this product will be removed from the corresponding document.
This document supersedes EN 573-3:2007.
Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 7 "Sheets,
strips and plates" to revise EN 573-3:2007.
CEN/TC 132 has decided to revise this standard every two years if necessary. The following modifications
have been introduced during the revision:
 Clause 3: the last sentence was re-written to be clear;
 Tables 1 to 8 and Tables A.1 to A.8: in the column "Chemical symbol", suffixes (A), (B) and (C) were
re-inserted;
 Table 5 and Table A.5 : in the column "Chemical symbol", the suffix (D) was re-inserted;
 Table 1 and Table A.1: alloy EN AW-1110 was added;
 Table 8 and Table A.8: alloys EN AW-8030 and EN AW-8176 were added.
 EN 573 comprises the following parts under the general title "Aluminium and aluminium alloys —
Chemical composition and form of wrought products":
 Part 1: Numerical designation system
 Part 2: Chemical symbol based designation system
 Part 3: Chemical composition and form of products
 Part 4: Forms of products
 Part 5: Codification of standardized wrought products
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies the chemical composition limits of wrought aluminium and wrought
aluminium alloys and form of products.
The chemical composition limits of aluminium and aluminium alloys specified herein are completely identical
with those registered with the Aluminum Association, 1525, Wilson Boulevard, Suite 600, Arlington, VA 22209,
USA, for the corresponding alloys.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 573-2, Aluminium and aluminium alloys — Chemical composition and form of wrought products —
Part 2: Chemical symbol based designation system
3 Chemical composition limits
The chemical composition of aluminium and aluminium alloys is specified in percentage by mass in Tables 1
to 8. Limits of impurities are expressed as a maximum; limits of alloying elements shown as a range
aluminium is specified as a minimum for unalloyed aluminium, and as a remainder for aluminium alloys.
The chemical composition of internationally registered wrought aluminium and wrought aluminium alloys not
listed in this document can be found in Teal sheet [1].
Analysis shall be made for elements which are specified, for example Pb, Sn, Bi, Sb, Zr.
4 Writing rules
4.1 Standard limits for alloying elements and impurities are expressed in percentage by mass to the
following decimal places:
 less than 0,001 % 0,000X;
 0,001 % but less than 0,01 % 0,00X;
 0,01 % but less than 0,10 %:
 unalloyed aluminium made by a refining process 0,0XX;
 others 0,0X;
 0,10 % to 0,55 % 0,XX;
 over 0,55 % 0,X; X,X; XX,X.
Exception: combined Si + Fe limits for 1xxx designations shall be expressed as 0,XX or 1,XX.
4.2 The aluminium content for unalloyed aluminium made by a refining process is the difference
between 100,00 % and the sum of all other metallic elements present in amounts of 0,0010 % or more each,
expressed to the third decimal place before determining the sum, which is rounded to the second decimal
place before subtracting.
For unalloyed aluminium not made by a refining process, the aluminium content is the difference
between 100,00 % and the sum of all other metallic elements present in amounts of 0,010 % or more each
expressed to the second decimal place before determining the sum.
5 Alloy designations
The numerical designation systems used in Teal sheets and European Standards for wrought aluminium
alloys are identical. As specified in EN 573-1 the prefix EN AW- is added.
The alternative chemical symbol based alloy designation system shall be based on EN 573-2.
Both the numerical and the chemical symbol based designations are indicated in Tables 1 to 8.
The International numerical system is the preferred one. The chemical symbol based designations are
indicated for reference only.
6 Sequence of elements
Standard limits for alloying elements and impurities are expressed in the following sequence: silicon, iron,
copper, manganese, magnesium, chromium, nickel, zinc, titanium, gallium, vanadium, remarks, other
elements each, other elements total, aluminium.
Limits of additional specified elements are inserted in alphabetical order of their chemical symbols under
“Remarks”.
7 Rounding rules for determination of compliance
In recording chemical analysis test results, the number representing the result for any element specified in this
standard shall be expressed to the same number of decimal places as the corresponding number in this
standard. For unalloyed aluminium, the aluminium content is derived as described in 4.2.
The following rounding rules shall be used for determination of compliance with this standard:
a) when the figure immediately after the last figure to be retained is less than 5, the last figure to be retained
remains unchanged;
b) when the figure immediately after the last figure to be retained is greater than 5, or equal to 5 and
followed by at least one figure other than zero, the last figure to be retained is increased by one;
c) when the figure immediately after the last figure to be retained is equal to 5 and followed by zeros only,
the last figure to be retained remains unchanged if even and is increased by one if odd.
