1.1 This specification covers aluminum and aluminum alloy flat sheet, coiled sheet, and plate in the alloys (Note 1) and tempers shown in Tables 2 and 3, and in the following finishes: 1.1.1 Plate in all alloys and sheet in heat-treatable alloys: mill finish. 1.1.2 Sheet in nonheat-treatable alloys: mill finish, one-side bright mill finish, standard one-side bright finish, and standard two-sides bright finish. 1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System (UNS) alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E 527. NOTE 1—Throughout this specification, use of the term alloy in the general sense includes aluminum as well as aluminum alloy. NOTE 2—See Specification B 632/B 632M for Tread Plate. NOTE 3—See Specification B 928/B 928M for 5xxx-H116 and 5xxx- H321 aluminum alloys containing 3 % or more nominal magnesium and intended for marine service and similar environments. Other alloy-temper products listed in Specification B 209, which do not require the additional corrosion testing/capability called out in Specification B 928/B 928M, may be suitable for marine and similar environment applications. 1.3 This specification is the metric counterpart of Specification B 209. 1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
