1. Scope*
1.1 This specification covers aluminum and aluminum-alloy extruded bars, rods, wire, profiles, and tubes 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 B211B211/B211M, for drawn seamless tube used in pressure applications,
Specification B210B210/B210M, for structural pipe and tube, Specification B429/B429M, and for seamless pipe and tube used in pressure applications,
Specification B241/B241M.
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 B210B210/
B210M or B241/B241M, or both as appropriate, for seamless pipe and tube used in fluid-carrying applications involving pressure. See Specification B234,
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 E527.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 A complete metric companion to Specification B221 has been developed—Specification B221M; therefore, no metric
equivalents are presented in this specification.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

A
The basis for establishment of tensile property limits is shown in Annex A1.
B
To determine conformance to this specification, each value shall be rounded to the nearest 0.1 ksi for strength and nearest 0.5 % for elongation in accordance with the
rounding-off-method of Practice E29.
C
Product type as specified in by Aluminum Association Registrations found in Yellow Sheets and AS&D
D
Elongation of full-section and cut-out sheet-type specimens is measured in 2 in. Elongation of cut-out round specimens is measured in 4× specimen diameter. See 8.1.1
and 8.1.2 for conditions under which measurements are not required.
E
These alloys are also produced in the F temper for which no tensile properties are specified or guaranteed.
F
For stress relieved tempers (T3510, T3511, T4510, T4511, T5510, T5511, T6510, T6511, T73510, T73511, T76510, T76511, T8510, T8511), characteristics and properties
other than those specified may differ somewhat from the corresponding characteristics and properties of material in the basic tempers.
G
Material in the T42 and T62 tempers is not available from the material producers.
H
Specified wall thickness range is limited to 2.999 in. This differs from Aluminum Standards and Data, which specifies wall thickness range as “All.”
I
Product type as specified in by Aluminum Association Registrations found in Yellow Sheets and AS&D Specified wall thickness range is limited to 2.999 in. This differs
from Aluminum Association Yellow Sheets, which specifies wall thickness range as 5.000 in for all extrusion products.
I
Yield strength is not applicable in tube.
J
Only in tube form.
K
Properties not applicable to extruded tube over 2.999 in wall thickness.
