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 the balance; The original table specifies no independent numerical range for Al. ; 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. ; Table 1, footnote 1: for welding electrodes and surfacing applications, beryllium content must not exceed 0.0008%.

Table 2, footnote b: Be≤0.0003% applies only to filler rods and welding wire; it is not a default restriction for all forms. ; Al is the balance; no independent numerical minimum is specified; Subtracting listed maxima from 100% must not be used to invent a minimum. ; Each otherwise unlisted element is ≤0.05%; this is not automatically treated as a known limit for a specific element. ; The combined total of otherwise unlisted elements is ≤0.15%. ; Table 1 applicable form: 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.

Table 2, footnote 2: Be≤0.0003% applies only to filler rods and welding wire; it is not a default restriction for all forms. ; Al is the balance; no independent numerical minimum is specified; Subtracting listed maxima from 100% must not be used to invent a minimum. ; Each otherwise unlisted element is ≤0.05%; this is not automatically treated as a known limit for a specific element. ; The combined total of otherwise unlisted elements is ≤0.15%. ; Table 1 applicable form: 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.
