Additional information

1. 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 . Seven alloy compositions are specified, designated as follows:

UNS^A	ASTM^A	Common	Traditional

Z33521	AG 40A	Alloy 3	Zamak 3
Z33522	AG 40B	Alloy 7	Zamak 7
Z35530	AC 41A	Alloy 5	Zamak 5
Z35540	AC 43A	Alloy 2	Zamak 2
Z35635			ZA-8
Z35630			ZA-12
Z35840			ZA-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 Specification B 86, 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.
