1050A
3 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.
Combined limits
- Purity calculation rules in the source
- PDF page references
- 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.
- Purity requires technical review
- Yes
- Other-impurity requirements in the source
- Each other impurity
- 0.03
- Other impurities require technical review

Applicability and limitations
Each otherwise unlisted element is ≤0.03%; this is not automatically treated as a known limit for a specific element. ; Table 1 applicable forms: extruded bars and cold-drawn bars; Form codes correspond only to Table 1 of this edition and do not establish supply by Creation Group. ; Table 2 gives chemical composition in mass percent; Mechanical properties, dimensions and delivery condition require separate verification against the applicable original tables and order requirements.
