    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.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. 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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other and values from the two systems shall not be combined.

    1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
