4 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.

Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Applicability and limitations

GB/T 3190—1996, Table 1, mass fraction %; unspecified elements are not treated as zero. This standard specifies the chemical composition of wrought aluminium and aluminium alloys; it does not automatically establish cold-heading suitability, actual supply, or finished-product performance. Al is the balance; the original table gives no independent numerical range for Al. Individual and total limits for other impurities apply only to the other elements referred to in clause 4.3, not to the sum of all principal alloying elements; a missing impurity test is not zero.

Verification notes

The original GB/T 3190—1996, Table 1 is used as an explicitly historical basis; The 2008/2020 edition cited in the original index has not been verified.
