scope:

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, C35350, and C35600. These alloys have nominal composition given in Table 1.

TABLE 1 Nominal Composition, %

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 ¹/₂ 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 B16/B16M and B140/B140M for copper-zinc-lead (leaded-brass) rod and bar for screw machine applications.
