(Specification)Standard Specification for Zinc Alloys in Ingot Form for Slush Casting
Standard Specification for Zinc Alloys in Ingot Form for Slush Casting
ABSTRACT
This specification covers two commercial zinc alloys, namely: Slush Casting Alloy A (Z34510) and Slush Casting Alloy B (Z30500), in ingot form for remelting for the manufacture of castings. This slush casting alloys are used primarily for the manufacture of hollow castings such as lighting fixtures, lamp bases, and small statues. The alloys may be made by any approved process, shall be of uniform quality, and shall be free from dross, slag, or other harmful contamination. The ingot shall be reasonably free of surface corrosion and adhering foreign matter. Casting alloys in black/red and black/orange color codes shall conform to the chemical composition requirements prescribed for copper, aluminum, lead, cadmium, tin, iron, magnesium, and zinc. The requirements for chemical composition verification such as number of samples, methods of sampling, and method of chemical analysis are given.
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 hollow castings such as lighting fixtures, lamp bases, and small statues.
1.3 This specification covers two zinc alloys which are specified and designated as follows:
UNSASTM Z34510Slush Casting Alloy A Z30500Slush Casting Alloy B
1.4 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.
1.5 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.
