1、Designation: B952/B952M 13B952/B952M 14Standard Specification forZinc Alloys in Ingot Form for Spin Casting1This standard is issued under the fixed designation B952/B952M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of
2、 last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers zinc alloys in ingot form for remelting for the manufacture of Spin Castings as specified
3、anddesignated, as shown in Table 1. Seven alloy compositions are specified, designated as follows:Common Traditional UNSSpin Casting Alloy SC-A . Z35550Spin Casting Alloy SC-B . Z35551Spin Casting Alloy SC-C . Z35534Spin Casting Alloy SC-D HJ10 Z35547Spin Casting Alloy SC-E HJ20 Z35548Spin Casting A
4、lloy SC-F HJ40 Z35552ZA-73 . Z365001.2 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 eachsystem may not be exact e
5、quivalents; therefore, each system shall be used independently of the other. Combining values from thetwo 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 responsibilityof the
6、user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety DataSheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, anddetermine the applicability of regulatory limit
