ASTM B221-08

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Profiles, and Tubes
This standard is issued under the fixed designation B 221; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
Note—Appendix and Table X1.1 updated and the year date was changed on Aug. 8, 2008.
1. Scope*
2
1.1 This specification covers aluminum and aluminum-alloy extruded bar, rod, wire, profile, and tube in the aluminum alloys
(Note 1) 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 B 211, for drawn seamless tube used in pressure applications, Specification
B 210, for structural pipe and tube, Specification B 429, and for seamless pipe and tube used in pressure applications, Specification B 241/B 241M.
NOTE 3—Structural pipe and tube produced in accordance with B 221 is not intended for fluid-carrying applications involving pressure. Refer to either
Specification B 210 or B 241/B 241M, as appropriate, for seamless pipe and tube used in fluid-carrying applications involving pressure.
1.2 Alloy and temper designations are in accordance with ANSI H35.1. 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 E 527.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 Acomplete metric companion to B 221 has been developed—B 221M; therefore, no metric equivalents are presented in this
specification.
