The chemical composition limits are tabulated by alloy and are the same for all wrought product forms in which the alloy is available. In addition, the tabulation is by alloy components in the case of alclad sheet, plate, and tubular products.5.Mechanical Property LimitsThe specified mechanical property limits are established for each wrought product; that is, sheet, plate, drawn tube, extruded shapes, pipe and extruded tube, rolled shapes, rod, bar, wire, and die forgings.6.Dimensional TolerancesThe dimensional tolerances to which aluminum alloy mill products are commercially produced are in accordance with the latest revision of the ANSI H35.2. For sizes outside commercial limits, the tolerance shall be as agreed upon by the supplier and purchaser.7.Standards for Chemical Composition and Mechanical Property LimitsThe American Society for Testing and Materials Standards and American National Standards in Table 1 contain the specified chemical composition limits, mechanical property limits, and material designations for each of the wrought products listed:8.Notes8.1Marginal IndiciaThe (R) is for the convenience of the user in locating areas where technical revisions have been made to the previous issue of the report.
