    ASTM B86

    1. Scope

    1.1 This specification covers commercial zinc, zinc-aluminum castings and continuous cast bar stock, as designated and specified in Table 1. Seven alloy compositions are specified and designated as follows:

    CommonTraditional ASTM&supA; UNS Alloy 3Zamak 3AG 40A&supB;Z33520Alloy 7Zamak 7AG 40BZ33523 Alloy 5Zamak 5AC 41A&supB;Z35531Alloy 2Zamak 2AC 43AZ35541ZA-8ZA-8...Z35636ZA-12ZA-12...Z35631ZA-27ZA-27...Z35841 &supA;See Table 1 , Footnote C.

    &supB;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. 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 the 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 Material Safety Data Sheet (MSDS) 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.
