1.1 This specification covers rolled or cold-finished bar, rod, and wire in alloys (Note 1) and tempers as shown in Table 2.

Note 1 - 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 B221 for aluminum and aluminum-alloy extruded bars, rods, wire, shapes, and tubes; and Specification B316/B316M for aluminum and aluminum-alloy rivet and cold-heading wire and rods.

1.2 Alloy and temper designations are in accordance with ANSI H35.1. The equivalent UNS alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E527.

1.3 A complete metric companion to Specification B211 has been developed-B211M; 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.
