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 alloyin 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 221 for aluminum and aluminum-alloy extruded bars, rods, wire, shapes, and tubes; and Specification B 316 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 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E 527.
1.3 A complete metric companion to Specification B 211 has been developed – B 211M; 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.
Keywords: aluminum alloy, rolled or cold-finished bar; rolled or cold finished rod; rolled or cold-finished wire; ICS Number Code 77.150.10 (Aluminium products), ASTM B211-03.
