Abstract
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.

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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
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, health, and environmental practices and determine the applicability of regulatory requirements prior to use.
1.4 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.
