GB/T 3190-2020 Chemical composition of wrought aluminium and aluminium alloys English Chemical composition of wrought aluminium and aluminium alloys 1 Scope This standard specifies the chemical composition of wrought aluminium and aluminium alloys. This standard is applicable to aluminium and aluminium alloy products (sheets, strips, foils, tubes, rods, shapes, wires and forgings, etc.) produced by pressure processing method, as well as ingots and blanks used for them. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The value of each element before summation shall be accurate to 0.0X%; ——When the content of "Al" element is greater than 99.90%~99.99%, by subtracting the sum of all elements under conventional analysis with the mass fraction not less than 0.0010% and the metal elements under unconventional analysis suspected of exceeding 0.0010% from 100.00%. The value of each element before summation shall be accurate to 0.0XX%, and the sum total after the summation shall be rounded off to 0.0X%; ——When the content of "Al" element is greater than 99.99%, by subtracting the sum of all elements under conventional analysis with the mass fraction not less than 0.0010% and the metal elements under unconventional analysis suspected of exceeding 0.0010% from 100.00%. The value of each element before summation shall be accurate to 0.00XX%, and the sum total after the summation shall be rounded off to 0.00X%.
