Description / Abstract:



1. Scope *

1.1 This specification covers aluminum-alloy (Note 1) die forgings, hand forgings, and rolled ring forgings as shown in Tables 1-3 and in 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 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 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 Table 4 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 developed--Specification B 247M; therefore, no metric equivalents are presented in this specification.
