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 B 16/B 16M, B 21/B 21M, B 98/B 98M, B 124/B 124M, B 138/B 138M, B 139/B 139M, B 140/B 140M, B 150/B 150M, B 151/B 151M, B 196/B 196M, B 283, B 301/B 301M, B 371/B 371M, B 411/B 411M, B 441, B 453/B 453M, B 455, B 570, and B 927 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 The values stated in inch-pounds units or SI units are to be regarded separately in the standard. Within the text the SI values are given in brackets. The values stated in each system of units are not exact equivalents; each system is independent of the other. Combining values from the two systems may result in nonconformance with the specification.

Note 1

Requirements for flat wire (defined as flat products up to and including 0.188 in. thick and up to 11/4 in. in width, with all surfaces rolled or drawn, without having been slit, sheared or sawed) including square, furnished in coils or straight lengths, or on spools, reels, or bucks are described by the wire Specifications B 206/B 206M and B 272.

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.


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.
