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).

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.
