ASTM B86-03

Standard Specification for Zinc and Zinc-Aluminum (ZA) Alloy Foundry and Die Castings

SCOPE
1.1 This specification covers commercial zinc and zinc-aluminum castings, as designated and specified in . Seven alloy compositions are specified and designated as follows:UNS ASTMCommonTraditionalZ33520AG 40A Alloy 3Zamak 3Z33523AG 40B Alloy 7Zamak 7Z35531AC 41A Alloy 5Zamak 5Z35541AC 43A Alloy 2Zamak 2Z35636ZA-8Z35631ZA-12Z35841ZA-27
See Table 1, Footnote B
SAE Specification, Nos. 903 and 925 conform to the requirements for alloys AG40A and AC41A, respectively.
1.2 Zinc Alloys Z33520, Z33523, Z35531, and Z35541 are used primarily in the manufacture of pressure die castings. Zinc-Aluminum Alloys Z35636, Z35631, and Z35841 are used in the manufacture of both foundry and pressure die castings.
1.3 The values stated in inch-pound units are to be regarded as the 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.
