ASTM B99/B99M-11

Standard Specification for Copper-Silicon Alloy Wire for General Applications

ABSTRACT
This specification establishes the requirements for round, rectangular, and square copper-silicon alloy wires with Copper Alloy UNS Nos. C65100 and 65500 for general applications other than electrical transmission cables. Tempers available under this specification are O61 (annealed), H00 (1/8 hard), H01 (¼ hard), H02 (½ hard), H04 (hard), and H08 (spring). Materials shall be tested and adhere to dimensional (mass, diameter, thickness, and width), mechanical (tensile and bending strength, and elongation), chemical composition, and grain size requirements.
SCOPE
1.1 This specification establishes the requirements for round, rectangular, and square wire for general applications other than for electrical transmission cable. The alloys involved are UNS Nos. C65100 and C65500.
1.2 Units—Values stated in either inch-pound units or SI 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 nonconformance with the standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
