(Specification)Standard Specification for Aluminum-Bronze Sand Castings
Standard Specification for Aluminum-Bronze Sand Castings
ABSTRACT
This specification establishes requirements for sand castings produced from copper-base alloys having the alloy numbers, commercial designations, and nominal compositions. The alloys the classified according to their nominal compositions: UNS No. C95200; UNS No. C95300; UNS No. C95400; UNS No. C95410; UNS No. C95500; UNS No. C95520; UNS No. C95600; UNS No. C95700; UNS No. C95800; UNS No. C95820; and UNS No. C95900. The castings shall conform to the chemical requirements specified. Mechanical properties shall be determined from separately cast test bar castings and shall meet the requirements. Brineel and Rockwell hardness readings shall be taken on the grip end of the tension test bar and shall be made in accordance with the specified requirements.
SCOPE
1.1 This specification establishes requirements for sand castings produced from copper-base alloys having the alloy numbers,2 commercial designations, and nominal compositions shown in Table 1.
1.2 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.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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.
