This specification establishes the requirements for copper (UNS Nos. C11000, C14500, and C14700) and copper alloy (UNS Nos. C36500, C37000, C37700, C46400, C48200, C48500, C61900, C62300, C63000, C63200, C64200, C64210, C65500, C67500, C67600, C69300, C70620, C71520, and C77400) forging rods, bars, and shapes. The material for manufacture shall be a cast rod, bar, or billet of such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in tempers H50 (extruded and drawn), M20 (as hot rolled), and M30 (as hot extruded). Products shall be tested and shall adhere to dimensional (diameter, thickness, width, length, shape, and straightness), mechanical, and chemical composition requirements.

Note 1—Additional information about forging practice and forgings produced from these alloys is given in Appendix X1 and in Specification B 283.

1.2 Units—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.

1.3 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 establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
