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.
Note 18212;Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.
Note 28212;See Specification B 632/B 632M for Tread Plate.
1.2 Alloy and temper designations are in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy designations are those of preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E 527.
1.3 A complete metric companion to Specification B 209 has been developed8212; B209M; therefore, no metric equivalents are presented in this specification.
