1. Scope
1.1 This specification establishes the requirements for copper-zinc-lead (leaded red brass or hardware bronze) rod, bar, and shapes of UNS Alloy Nos. C31400, C31600, and C32000 available for screw machine applications.
1.2 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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
