Abstract:

This specification establishes the general requirements common to several wrought products including copper and copper-alloy plates, sheets, strips, and rolled bars. The numerical values in this specification are not presented in metric or SI units, but rather, in inch-pound units only. The material for manufacture shall be a cast bar, cake, or slab of such purity and soundness as to be suitable for processing by hot- or cold-working, and annealing to produce a uniform wrought structure in the finished product. The edges shall be slit, sheared, sawed, or rolled, as specified. When rolled edges are required, they may be produced by either rolling or drawing to one of the following specified edge contours: square edges (square corners), rounded corners, rounded edges, and full-rounded edges. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, length, width, weight, and straightness), mechanical (tensile and yield strength, Rockwell hardness, and elongation), electrical (resistivity and conductivity), chemical composition, and grain size requirements.

Scope:

1.1 This specification establishes the general requirements common to several wrought product specifications. Unless otherwise specified in the purchase order or in an individual specification, these general requirements shall apply to copper and copper-alloy plate, sheet, strip, and rolled bar supplied under each of the following product specifications issued by ASTM: B 36/B 36M, B 96/B 96M, B 103/B 103M, B 121/B 121M, B 122/B 122M, B 152/B 152M, B 169/B 169M, B 194, B 422, B 465, B 534, B 591, B 592, B 694, B 740, B 747, and B 768.

Note 1

A complete metric companion to Specification B 248 has been developed-B 248M; therefore no metric equivalents are presented in this specification.

1.2 Units - This specification is the companion specification to SI Specification B 248M; therefore, no SI equivalents are shown in this specification.
