Abstract

This specification covers the material, chemical and mechanical requirements for aluminum-alloy castings produced by the thixocast, rheocast, semi-solid and squeeze casting processes. It does not apply to castings used in aerospace applications. Castings shall conform to the chemical composition limits and tensile properties specified for each alloy designation, and those produced for governmental or military agencies, or both, shall additionally adhere to specified material and foundry control requirements. Castings shall also pass quality checks based on the following attributes: imperfections; internal soundness; pressure tightness; fillets, ribs, and corners; ejector pins, pin marks, pin flash, and flash removal; casting flash removal; surface finish; die cast lettering and ornamentation; machining stock allowances; and workmanship. Heat treatment and repair recommendations are also included herein.

Scope

1.1 This specification covers aluminum-alloy castings, produced by the thixocast, rheocast, semi-solid and squeeze casting processes, shown in Table 1.

1.2 This specification is not intended for castings used in aerospace applications.

1.3 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent unified numbering system alloy designations are in accordance with Practice E527.

1.4 Unless the order specifies the M specification designation, the material shall be furnished to the inch-pound units.

1.5 For acceptance criteria for inclusion of new aluminum and aluminum alloys and their properties in this specification, see Annex A1 and Annex A2.

1.6 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.

1.7 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.
