1 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 percent; Unspecified elements are not treated as zero. ; This standard covers chemical composition of wrought aluminum and aluminum alloys; This does not establish cold-heading suitability, actual supply or finished-product properties. ; Al is listed as a minimum content; Aluminum content is calculated by difference under Clause 4.1/4.2, using the specified inclusion thresholds and precision; unmeasured elements must not be treated as zero. ; Individual and combined limits for other impurities concern only the other elements defined in Clause 4.3 of the standard, not the sum of all principal alloying elements; Missing impurity test results must not be treated as zero.

- 3
- Purity from 99.00% to below 99.90%
- Al = 100 minus the sum of all other elements present at ≥0.010%; before summing, express each element to 0.0X%.
- Purity from 99.90% to 99.99%
- Al = 100 minus the sum of all other elements present at ≥0.001%; before summing, express each element to 0.00X%, then round the result to 0.0X%.
- Rounding rules
- Follow GB/T 8170; do not treat unspecified elements as zero or apply ordinary remainder calculations directly.
