ASTM B952/B952M-14

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: B952/B952M − 13 B952/B952M − 14
Standard Specification for
1
Zinc Alloys in Ingot Form for Spin Casting
This standard is issued under the fixed designation B952/B952M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of 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 and
designated, as shown in Table 1. Seven alloy compositions are specified, designated as follows:
Common Traditional UNS
Spin Casting Alloy SC-A . Z35550
Spin Casting Alloy SC-B . Z35551
Spin Casting Alloy SC-C . Z35534
Spin Casting Alloy SC-D HJ10 Z35547
Spin Casting Alloy SC-E HJ20 Z35548
Spin Casting Alloy SC-F HJ40 Z35552
ZA-73 . Z36500
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.
