ASTM B308 / B308M

This specification covers the standard structural profiles for 6061-T6 aluminum-alloy. The profiles are limited to I-beams, H-beams, channels, angles, tees, and zees, which shall be produced by hot extruding only. Chemical composition and tensile properties such as tensile strength, yield strength, and elongation shall conform to the limits herein provided. The determination of chemical composition shall be made in accordance with suitable chemical or spectrochemical methods. Tensile properties shall be tested with test methods for tension testing wrought and cast aluminum- and magnesium-alloy products.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers extruded 6061-T6 aluminum-alloy standard structural profiles.

1.2 The profiles are limited to I-beams, H-beams, channels, angles, tees, and zees.

Note 1—For other extruded profiles in other alloys and tempers refer to Specification B 221.

1.3 Alloy and temper designations are in accordance with ANSI H35.1 and ANSI H35.1(M). The equivalent Unified Numbering System alloy designation is that in preceded by A9, or A96061 for alloy 6061 in accordance with Practice E 527.

1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see .

1.5 The values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems will result in nonconformance with the specification.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
