Abstract
This specification covers rolled or cold-finished bar, rod, and wire in alloys and tempers. The products shall be produced either by hot extruding and cold finishing or by hot rolling with or without cold finishing. The bars, rods, and wire shall conform to the chemical composition limits specified. Samples for determination of chemical composition shall be taken in accordance with one of the following methods: chemical analysis or spectrochemical analysis. The bar, rod, and wire shall conform to the tensile requirements. Bend testing and stress-corrosion resistance test shall be made to conform to the specified requirements.
Scope
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 3See 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.
