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);

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
“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:
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
