3102

GB/T3880.1—2006 Table 5 and 4.2, mass fraction %; Only 3102, 3104, and 8011A have compositions directly specified in this table; other grades refer to GB/T3190 and cannot be copied from this table. Applicable to rolled aluminum and aluminum alloy plate, sheet and strip for general industrial use.; The scope of this edition excludes special uses such as deep drawing, painting, anodizing, curtain walls and PS plate substrates, as well as plate, sheet and strip for military applications; it does not directly establish cold-heading wire/wire rod suitability.. Other impurities: individual ≤0.05%, total ≤0.15%, referring to metallic elements not listed or with no specified values in the table; these must be verified separately against the full set of measured values. Al is the remainder: 100% minus the sum of all metallic impurities with content ≥0.010%; each element shall be expressed to 0.0X% before summation; Elements with no given values must not be assumed as zero for calculation. Use for food applications must be specified in the contract, with Pb, Sn and Sb each ≤0.01%.; The conditions for this use require separate verification; food-application limits are not imposed on all industrial materials.. The chemical table and scope have been verified in this instance; this does not imply that mechanical properties, dimensions, states of all grades, or the 2012 edition have been verified.
