This specification covers aluminum and aluminum-alloy die forgings, hand forgings, and rolled ring forgings and includes the following UNS alloy designations: A91100, A92014, A92018, A92025, A92219, A92618, A93003, A94032, A95083, A96061, A96066, A96151, A97049, A97050, A97075, A97076, and A97175. Tempers covered by this specification includes: H112, T4, T6, T61, T73, T74, T7352, T7452, T7454, T652, T852, and H111 as well as F and 01 types. The forgings may be manufactured by pressing, hammering, or rolling, at the option of the producer. Requirements for quality assurance, chemical analysis, tension and hardness tests, heat treatment, heat-treat response, and stress corrosion resistance and stress-corrosion cracking test are detailed. The forgings shall conform to the chemical composition requirements prescribed for aluminum, silicon, iron, copper, manganese, magnesium, chromium, nickel, zinc, zirconium, and titanium. Forgings having the specified thickness shall meet the requirements specified for the mechanical properties such as tensile strength, yield strength, elongation, and Brinell hardness.
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 aluminum-alloy ( ) die forgings, hand forgings, and rolled ring forgings as shown in , , and in Section for heat-treatable alloy forgings supplied in the F and 01 tempers. The maximum thicknesses for forgings within the scope of this specification are as indicated in those tables.
Note 1: Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.
Note 2: For forging stock supplied as rolled, cold-finished bar, extruded bar, or rod see Specification .
1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System alloy designations are those of 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 This specification is the inch-pound companion to Specification ; therefore, no SI equivalents are presented in the 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.
