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 inch-pound units, but rather, in metric or SI 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.

Significance and Use

For the purposes 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 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: B36/B36M , B96/B96M , B103/B103M , B121/B121M , B122/B122M , B152/B152M , B169/B169M , B194 , B422 , B465 , B534 , B591 , B592 , B694 , B740 , B747 , B768 , and B888 .

1.2 Units This specification is the companion specification to inch-pound Specification B248 .
