(Specification)Standard Specification for Zinc Alloys in Ingot Form for Spin Casting
Standard Specification for Zinc Alloys in Ingot Form for Spin Casting
ABSTRACT
This specification covers four zinc alloys in ingot form, namely: Spin Casting Alloy SC-A, Spin Casting Alloy SC-B, Spin Casting Alloy SC-C, and ZA-73, for remelting for the manufacture of spin castings. The alloys may be made by any approved process, shall be of uniform quality, and shall be free from dross or other harmful contamination. The ingots shall conform to the chemical composition limits prescribed for aluminum, magnesium, copper, iron, lead, cadmium, tin, nickel, and zinc. Chemical analysis requirements for determination and for verification (if needed) of chemical composition are detailed.
SCOPE
1.1 This specification covers zinc alloys in ingot form for remelting for the manufacture of Spin Castings as specified and designated, as shown in Table 1. Seven alloy compositions are specified, designated as follows:
CommonTraditionalUNS Spin Casting Alloy SC-A...... Spin Casting Alloy SC-B...... Spin Casting Alloy SC-C...... Spin Casting Alloy SC-DHJ10... Spin Casting Alloy SC-EHJ20... Spin Casting Alloy SC-FHJ40... ZA-73......
1.2 Zinc alloys #2, #3, #5, and ZA-8 specified in Specification B240 are also used in the spin casting process.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with 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 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.
