Foreword
This Standard was drafted in accordance with the rules in GB/T 1.1-2009.
This Standard serves as a replacement of GB/T 3190-2008 Wrought Aluminum and
Aluminum Alloy - Chemical Composition. In comparison with GB/T 3190-2008, apart
from editorial modifications, the main technical changes are as follows:
---Normative References are modified (see Chapter 2; Chapter 2 of Version 2008);
---In the table of International Four-digit Designations and Chemical Composition,
79 designations are added; 6 designations are deleted (see 3.1.1; 3.1.1 of
Version 2008);
---In the table of Domestic Four-character Designations and Chemical
Composition, 29 designations are added; Designation - 2A97 is deleted (see
3.1.1; 3.1.1 of Version 2008);
---The header of the table of International Four-digit Designations and Chemical
Composition and the table of Domestic Four-character Designations and
Chemical Composition is modified; eight element columns are added: “Ag”, “B”,
“Bi”, “Ga”, “Li”, “Pb”, “Sn” and “V” (see 3.1.1; 3.1.1 of Version 2008);
---The control requirements for aluminum and aluminum alloy materials for
packaging are added (see 3.1.5);
---The requirements for sampling are modified (see 3.2; 3.2 of Version 2008);
---The requirements for component analysis are modified (see 3.3; 3.3 of Version
2008);
---The designations and chemical compositions of inactive alloys are added (see
Appendix A);
---A Comparison Table of Previously Used Designations is modified (see Appendix
B; Appendix A of Version 2008).
This Standard was proposed by China Nonferrous Metals Industry Association.
This Standard shall be under the jurisdiction of National Technical Committee 243 on
Nonferrous Metals of Standardization Administration of China (SAC/TC 243).

Chemical Composition of Wrought Aluminum and
Aluminum Alloys
1 Scope
This Standard stipulates the chemical composition of wrought aluminum and aluminum
alloys.
This Standard is applicable to aluminum and aluminum alloy processed products
(sheets, strips, foils, pipes, rods, profiles, wires and forgings, etc.) manufactured by the
method of pressure machining, as well as the ingots and billets used.

3 Requirements
3.1 Chemical Composition
3.3.1 Merely conduct routine analysis on the elements specified in the values other
than “Al” and “Others” in Table 2, Table 3 and Table A.1. When it is suspected that the
mass fraction of non-routine analysis elements exceeds the limits of this Standard, the
producer shall analyze these elements.
3.3.2 The chemical composition analysis method in Table 2, Table 3 and Table A.1 shall
comply with the stipulations of GB/T 20975, GB/T 7999 or YS/T 870. In terms of
designations whose “Co” element content is less than 0.005%, or, designations whose
“Al” element content is not less than 99.90%, the arbitration analysis of chemical
composition shall adopt the method specified by YS/T 870. The arbitration analysis of
“O” element content may also be determined through negotiation between the
demand-side and the supply-side. The arbitration analysis of the remaining chemical
compositions shall adopt the method specified by GB/T 20975.
3.3.3 When calculating “the sum” of “others” in Table 2, Table 3 and Table A.1, before
the summation, the various element analysis values shall be expressed to 0.XX%.
3.3.4 In Table 2, Table 3 and Table A.1, “Al” element content which is ≥ 99.00% shall
be determined through the method of calculation:
---When “Al” element content is ≥ 99.00% ~ 99.90 %, use 100.00% to minus the
sum of all the routine analysis elements with a mass fraction of not less than
0.010% and non-routine analysis metal elements that are suspected of being
excessive. Before the summation, the various element values shall be
expressed to 0.0X%;
---When “Al” element content is > 99.90% ~ 99.99%, use 100.00% to minus the
sum of all the routine analysis elements with a mass fraction of not less than
0.0010% and non-routine analysis metal elements that are suspected of being
excessive. Before the summation, the various element values shall be
expressed to 0.0XX%. After the summation, the sum shall be rounded off to
0.0X%;
---When “Al” element content is > 99.99%, use 100.00% to minus the sum of all
the routine analysis elements with a mass fraction of not less than 0.0010%
and non-routine analysis metal elements that are suspected of being excessive.
Before the summation, the various element values shall be expressed to
0.00XX%. After the summation, the sum shall be rounded off to 0.00X%.
3.3.5 The determination of analysis values shall adopt the round-off comparison
method. The round-off rules of numerical values shall comply with relevant stipulations
of GB/T 8170. The rounded-off digits shall be consistent with the limit digits specified
in Table 2, Table 3 and Table A.1 in this Standard.
3.3.6 The manufacturer shall conduct supervision and control analysis of the control
elements in 3.1.3, 3.1,4 and 3.1.5, so as to ensure that the control elements comply
