ASTM B209M-04

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 H35.1M. The equivalent Unified Numbering System (UNS) alloy designations are those of preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E 527.

Note 1 - Throughout this specification, use of the term alloyin 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 the additional corrosion testing required, it is not intended that Specification B 209M be used for marine sheet and plate.

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.
