ASTM B 209 : 2006

1.1 This specification covers aluminum and aluminum-alloy flat sheet, coiled sheet, and plate in the alloys (Note 1) and tempers shown in Table 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 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 marine sheet and plate. Due to additional corrosion testing required, it is not intended that Specification B 209 be used for marine sheet and plate.

1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System alloy designations are those of Table 1 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 developed-Specification B 209M; therefore, no metric equivalents are presented in this specification.

1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
