Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
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, 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.
