1.1 This specification covers commercial zinc, zinc-aluminum castings and continuous cast bar stock, as designated and specified in Table 1 . Eight alloy compositions are specified and designated as follows: Common Traditional ASTM A UNS Alloy 3 Zamak 3 AG 40A B Z33525 Alloy 7 Zamak 7 AG 40B Z33527 Alloy 5 Zamak 5 AC 41A B Z35533 Alloy 2 Zamak 2 AC 43A Z35545 ZA-8 ZA-8 . Z35638 ZA-12 ZA-12 . Z35633 ZA-27 ZA-27 . Z35841 ACuZinc 5 C . Z46541 1.2 Zinc Alloys Z33525, Z33527, Z35533, and Z35545 are used primarily in the manufacture of pressure die castings. Zinc-Aluminum Alloys Z35638, Z35633, and Z35841 are used in the manufacture of both foundry and pressure die castings. These alloys are also fabricated into continuous cast bar stock used for prototyping and screw machine stock. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 Systems of nomenclature used to designate zinc and zinc-aluminum (ZA) alloys used for casting are described in Appendix X1 . 1.5 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 Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 1.6 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.
