Abstract

This specification covers aluminum-alloy die forgings, hand forgings, and rolled ring forgings. The forgings may be manufactured by pressing, hammering, or rolling. The forgings shall conform to the chemical composition limits specified. Samples for determination of chemical composition shall be taken in accordance with one of the following methods: chemical analysis or spectrochemical analysis. Tension test, Brinell hardness test and stress corrosion resistance test shall be made to conform to the specified requirements.

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 aluminum-alloy (Note 1) die forgings, hand forgings, and rolled ring forgings as shown in Table 2, Table 3 and Table 4in Section 10 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 1Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.

Note 2For forging stock supplied as rolled or cold-finished bar or rod see Specification B 211. For forging stock supplied as extruded bar or rod see Specification B 221.

1.2 Alloy and temper designations are in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy designations are those of 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 A complete metric standard to Specification B 247 has been developedSpecification B 247M; therefore, no metric equivalents are presented in this specification.
