ASTM B618-03

Standard Specification for Aluminum-Alloy Investment Castings

SCOPE
1.1 This specification covers aluminum-alloy investment castings designated as shown in Table 1.
1.2 This specification is not intended for aluminum-alloy investment castings used in aerospace applications.
1.3 Alloy and temper designations are in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy designations are in accordance with Practice E 527.
1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys and their properties in this specification, see Annex A1 and Annex A2.
1.5 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.
1.6 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.
