CONTAINED IN VOL. 02.04, 2017 Specifies commercial zinc and zinc-aluminum (ZA) alloys in ingot form for remelting for the manufacture of pressure die castings, foundry castings and continuous cast bar stock.

1.1This specification covers commercial zinc and zinc-aluminum (ZA) alloys in ingot form for remelting for the manufacture of pressure die castings, foundry castings and continuous cast bar stock as designated and specified in Table 1. Seven alloy compositions are specified, designated as follows:

(A)See Table 1, footnote B.
(A)Zinc alloy ingot for die casting may contain nickel, chromium, silicon, and manganese in amounts of up to 0.02, 0.02, 0.035 and 0.05 %, respectively. No harmful effects have ever been noted due to the presence of these elements in up to these concentrations and, therefore, analyses are not required for these elements, except that nickel analysis is required for Z33526.
(B)ASTM alloy designations were established in accordance with Practice B275. UNS assignations were established in accordance with Practice E527. The last digit of a UNS number differentiates between alloys of similar composition. UNS designations for ingot and casting versions of an alloy were not assigned in the same sequence for all alloys.
(C)For purposes of acceptance and rejection, the observed value or calculated value obtained from analysis should be rounded to the nearest unit in the last right-hand place of figures, used in expressing the specified limit, in accordance with the rounding procedure prescribed in Practice E29.
(D)When this material is required to conform to ISO Standard 301, the chemical limits for thallium and indium each shall not exceed 0.001 %.
(E)Zinc-aluminum ingot for foundry and pressure die casting may contain nickel, chromium, and manganese in amounts of up to 0.01 % each or 0.03 % total. No harmful effects have ever been noted due to the presence of these elements in up to these concentrations and, therefore, analyses are not required for these elements.
(F)Refer to Practice B908. (Note: Colors indicated are for North American applications.)
(G)Determined arithmetically by difference.

1.2Zinc alloys Z33524, Z33526, Z35532, Z46540, and Z35544 are used primarily for remelting in the manufacture of pressure die castings. Zinc-aluminum alloys Z35637, Z35632, and Z35842 are used for remelting in the manufacture of both foundry and pressure die castings. Castings made from these ingots are specified in Specification B86, Standard Specification for Zinc and Zinc-Aluminum Alloys for Foundry and Die Castings.

1.3The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

1.4Systems of nomenclature used to designate zinc and zinc-aluminum (ZA) alloys used for casting are described in Appendix X1.

1.5This 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.

1.6This 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.
