(Specification)Standard Specification for Copper-Silicon Alloy Rod, Bar and Shapes
Standard Specification for Copper-Silicon Alloy Rod, Bar and Shapes
ABSTRACT
This specification covers rods, bars, and shapes of copper-silicon alloys with UNS Alloy UNS Nos. C65100, C65500, and C66100. The starting materials shall be cast billets or rods of such soundness and structure as to enable them to be processed by hot working, cold working, straightening, and annealing to produce a uniform wrought structure in the finished product. Tempers available under this specification are O60 (soft annealed), H01 (¼-hard), H02 (½-hard), H04 (hard), H06 (extra-hard), M20 (as hot rolled), and M30 (as hot extruded). Products shall be tested and shall adhere to dimensional (mass, diameter, shape, length, straightness, and edge contour), mechanical (tensile and yield strength, elongation, and Rockwell hardness), and chemical composition requirements.
SCOPE
1.1 This specification establishes requirements for copper-silicon rod, bar, and shapes for UNS Copper Alloys C65100, C65500, and C66100.Note 1—Material for hot forging is covered by Specification B124/B124M.Note 2—For ASME Boiler and Pressure Vessel Code applications, see Specification SB-98 in Section II of that code.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, SI units are shown in brackets. 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.
