Historical (view previous versions of standard)
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.
1.1 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 B221.
1.3 Alloy and temper designations are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Numbering System alloy designation is that in Table 1 preceded by A9, or A96061 for alloy 6061 in accordance with Practice E527.
1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
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.
