Standard Specification for Aluminum and Aluminum-Alloy Bar, Rod, and Wire [Metric]

SCOPE
1.1 This specification covers rolled or cold-finished bar, rod, and wire in alloys (Note 1) and tempers as shown in .
Note —Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.Note 2—The term cold finished is used to indicate the type of surface finish, sharpness of angles, and dimensional tolerances produced by drawing through a die.
Note 3—See Specification B 221M for aluminum and aluminum-alloy extruded bars, rods, wire, shapes, and tubes; and Specification B 316M for aluminum and aluminum-alloy rivet and cold-heading wire and rods.
1.2 Alloy and temper designations are in accordance with ANSI H35.1M. 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 This specification is the metric counterpart of Specification B 211.
1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
