ASTM B240-01

Standard Specification for Zinc and Zinc-Aluminum (ZA) Alloys in Ingot Form for Foundry and Die Castings

SCOPE
1.1 This specification covers commercial zinc and zinc-aluminum (ZA) alloys in ingot form for remelting for the manufacture of pressure die castings and foundry castings as designated and specified in Table 1. Seven alloy compositions are specified, designated as follows:UNSAASTMA CommonZ33521AG 40AAlloy 3Z33522AG 40BAlloy 7Z35530AC 41AAlloy 5Z35540AC 43AAlloy 2Z35635ZA-8Z35630ZA-12Z35840ZA-27
1.2 Zinc alloys Z33521, Z33522, Z35530, and Z35540 are used primarily for remelting in the manufacture of pressure die castings. Zinc-aluminum alloys Z35635, Z35630, and Z35840 are used for remelting in the manufacture of both foundry and pressure die castings. Castings made from these ingots are specified in ASTM B86, Standard Specification for Zinc and Zinc-Aluminum Alloys for Foundry and Die Castings.
1.3 The values stated in inch-pound units are to be regarded as standard.
1.4 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 become familiar with all hazards including those identified in the appropriate Material Data Sheet for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
