ASTM B453/B453M-08

1.1 This specification establishes the requirements for copper-zinc-lead alloy (leaded-brass) rod, bar, wire, and shapes produced from Copper Alloys UNS Nos. C33500, C34000, C34500, C35000, C35300, C35330, and C35600. These alloys have nominal composition given in Table 1.

1.1.1 This product is suitable for applications requiring extensive machining before such cold-forming operations as swaging, flaring, severe knurling, or thread rolling.

Note 1 - Refer to Appendix X1 for additional applications information.

1.1.2 Typically, product made to this specification is furnished as straight lengths. Sizes ½ in. [12 mm] and under may be furnished as wire in coils or on reels when requested.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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 non-conformance with the standard.

Note 2 - Refer to Specifications B 16/B 16M and B 140/B 140M for copper-zinc-lead (leaded-brass) rod and bar for screw machine applications.
