1.1 This specification establishes requirements for copper-silicon rod, bar, and shapes for UNS Alloys C65100 (Low Silicon Bronze B), C65500 (High Silicon Bronze A), and C66100.

Note 1-Material for hot forging is covered by Specification B 124.

1.2 The values stated in inch-pound units or SI units are to be regarded seperately 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.
