ASTM-B221 › Standard Specification for Aluminum and Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers extruded bars, rods, wires, profiles, and tubes made from aluminum and aluminum alloys. All the products should be produced by hot extrusion or similar methods. The chemical composition of each material is determined in accordance with the specified suitable chemical and spectrochemical test methods. Samples for chemical analysis should be taken when the ingots are poured or from the finished or semi-finished products by drilling, sawing, milling, turning, or clipping. Tensile properties, elongation, and yield strengths of each product should conform to the requirements listed herein. Elongation requirements are not applicable for materials with sizes smaller than the specified limits.

1.1 This specification covers aluminum and aluminum-alloy extruded bars, rods, wire, profiles, and tubes in the aluminum alloys ( ) and tempers shown in Table 2.
Note 1: Throughout this specification, the use of the term alloy in the general sense includes aluminum as well as aluminum alloy.
Note 2: For rolled or cold-finished bar and rod refer to Specification , for drawn seamless tube used in pressure applications, Specification , for structural pipe and tube, Specification , and for seamless pipe and tube used in pressure applications, Specification .
Note 3: Pipe and tube products listed in this specification are intended for general purpose applications. This specification may not address the manufacturing processes, integrity testing, and verification required for fluid-carrying applications involving pressure. See Specifications or , or both as appropriate, for seamless pipe and tube used in fluid-carrying applications involving pressure. See Specification , as appropriate, for use in surface condensers, evaporators, and heat exchangers.
1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9; for example, A91100 for Aluminum 1100 in accordance with Practice .
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see .
1.4 A complete metric companion to Specification has been developed—Specification ; therefore, no metric equivalents are presented in this specification.
