This specification establishes requirements for coppersilicon rod, bar, and shapes for UNS Alloys C65100, C65500,and C66100.The values stated in inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
