Standard Specification for Copper-Zinc-Lead Alloy (Leaded-Brass) Rod, Bar, and Shapes
ABSTRACT
This specification establishes the requirements for rods, bars, wires, and shapes of copper-zinc-lead alloys (leaded-brass) with Copper Alloy UNS Nos. C33500, C34000, C34500, C35000, C35300, and C35600. The products to which this specification applies is suitable for applications requiring extensive machining before such cold-forming processes as swaging, flaring, severe knurling, or thread rolling. Products shall be produced in tempers O60 (soft annealed), H01 (1/4 hard), and H02 (1/2 hard). Products shall be tested to examine their conformance to dimensional (diameter, shape, length, and straightness), mechanical (tensile and yield strength, Rockwell hardness, and elongation), and chemical composition requirements.
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.
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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
Note 2: Refer to Specifications B16/B16M and B140/B140M for copper-zinc-lead (leaded-brass) rod and bar for screw machine applications.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
