Abstract

This specification establishes the general requirements common to wrought copper and copper alloy rods, bars, shapes, and forgings. Products shall be manufactured by hot working, cold working, or both, and finished by cold working, annealing, or heat treatment and straightening as identified necessary to meet the properties specified. Materials shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, diameter, length, straightness, and edge contours), mechanical (tensile strength, Rockwell hardness, elongation, and hydrogen embrittlement), electrical resistivity, chemical composition, and grain size requirements. The products shall also meet performance requirements when subjected to residual stress, mercurous nitrate, ammonia vapor, and semiguided bend tests. In the event of conflict between this specification and the individual casting product specifications, the requirements of the casting specification shall take precedence.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Significance and Use

For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table and for dimensional tolerances, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29 .

1. Scope

1.1 This specification establishes the general requirements common to wrought copper and copper alloy rod, bar, shapes, and forgings which shall apply to Specifications B16/B16M , B21/B21M , B98/B98M , B124/B124M , B138/B138M , B139/B139M , B140/B140M , B150/B150M , B151/B151M , B187/B187M , B196/B196M , B283/B283M , B301/B301M , B371/B371M , B411/B411M , B441 , B453/B453M , B455 , B570 , B870 , B927/B927M , B929 , B967/B967M , and B974/B974M to the extent referenced therein.

1.2 The chemical composition, physical and mechanical properties, and all other requirements not included in this specification are prescribed in the product specification.

1.3 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.

1.3.1 Within the text the SI values are given in brackets.

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