Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate [Metric]
This specification covers aluminum and aluminum alloy flat sheet, coiled sheet, and plate in the alloys and tempers in the following finishes: Plate in all alloys and sheet in heat-treatable alloys which are mill finished; and sheet in non heat-treatable alloys which are mill finished, one-side bright mill finished, standard one-side bright finished, and standard two-sides bright finished. The producer is responsible for the performance of all inspection and test requirements unless specified in the contract. The material shall be supplied in the mill finish and shall be uniform as defined by the requirements of this specification and shall be commercially sound. Each sheet and plate shall be examined to determine conformance to this specification with respect to general quality and identification marking. Sheet and plate shall be capable of being bent cold through a specified angle around a pin without cracking for the different alloys, tempers, and thicknesses. The plates shall exhibit no evidence of stress-corrosion cracking. For lot-acceptance purposes, resistance to exfoliation corrosion for each lot of material in the alloys and tempers shall be established by testing the previously selected tension-test samples to the criteria. The material shall be packaged to provide adequate protection during normal handling and transportation and each package shall contain only one size, alloy, and temper of material unless otherwise agreed.
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 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.
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.
