Standard Specification for Aluminum and Aluminum-Alloy Die Forgings, Hand Forgings, and Rolled Ring Forgings [Metric]

SCOPE
1.1 This specification covers aluminum-alloy (Note 1) die forgings, hand forgings, and rolled ring forgings as shown in Tables 2, 3, and 4 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 B211M. For forging stock supplied as extruded bar or rod see Specification B221M.
1.2 Alloy and temper designations are in accordance with ANSI H35.1M. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E527.  
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 This specification is the metric counterpart of Specification B247.
