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. Four alloy compositions are specified, designated as follows:
|Spin Casting Alloy SC-A||...|
|Spin Casting Alloy SC-B||...|
|Spin Casting Alloy SC-C||...|
1.2 Zinc alloys #2, #3, #5, and ZA-8 specified in Specification B 240 are also used in the spin casting process.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
