(Specification)Standard Specification for Zinc Alloys in Ingot Form for Slush Casting
Standard Specification for Zinc Alloys in Ingot Form for Slush Casting
SCOPE
1.1 This specification covers commercial zinc alloys in ingot form for remelting for the manufacture of castings from the alloys as specified and designated as shown in Table 1.
1.2 Slush casting alloys are used primarily for the manufacture of lighting fixtures, lamp bases, and small statues.
1.3 This specification covers two zinc alloys which are specified and designated as follows: UNSASTMZ34510Slush Casting Alloy AZ30500Slush Casting Alloy B
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.
