Annotation of standard text ASTM B969/B969M-18e1 :

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.

Additional information

1. Scope

1.1 This specification covers aluminum-alloy castings, produced by Squeeze Casting, and the Semi-Solid Thixocast and Rheocast casting processes, designated as shown in Table 1.

1.2 This specification is for aluminum-alloy squeeze castings, and semi-solid Thixocast and Rheocast castings used in general purpose applications. It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications.

1.3 Alloy and temper designations are in accordance with ANSI H35.1/H35.1 (M).

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.

1.8 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.
