(Specification)Standard Specification for General Requirements for Wrought Copper and Copper-Alloy Rod, Bar, Shapes and Forgings
Standard Specification for General Requirements for Wrought Copper and Copper-Alloy Rod, Bar, Shapes and Forgings
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.
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.

Calculated Value Chemical compositionnearest unit in the last right-hand significant digit used in expressing the limiting value Hardness Electrical resistivity Electrical conductivity Tensile strengthnearest ksi [5 MPa] Yield strength Elongation:nearest 1 % Grain size: Under 0.060 mmnearest multiple of 0.005 mm 0.060 mm and overnearest 0.01 mm
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, B196/B196M, B283, B301/B301M, B371/B371M, B411/B411M, B441, B453/B453M, B455, B570, and B927 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 either SI units or inch-pounds 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 independent 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.
Note 1—Requirements for flat wire (defined as flat products up to and including 0.188 in. thick and up to 1¼ 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 B206/B206M and B272.
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.
