This specification establishes the requirements for copper-zinc-lead (leaded red brass or hardware bronze) rods, bars, and shapes of UNS Alloy Nos. C31400, C31600, and C32000 used for screw machine applications. Tempers available to this specification are O60 (soft anneal), H02 (half-hard), and H04 (hard). Materials for manufacture shall be cast billets, logs, or rods of such purity and soundness as to be suitable for processing by hot working, cold-working, straightening, and annealing to produce a uniform wrought structure in the finished product. Tempers available under this specification are O60 (soft anneal), H02 (half-hard), and H04 (hard). Products shall be tested and conform to dimensional (mass, diameter, length, straightness, and shape), mechanical (tensile and yield strength, and elongation), and chemical composition requirements.

1.1 This specification establishes the requirements for copper-zinc-lead (leaded red brass or hardware bronze) rod, bar, and shapes of UNS Copper Alloy Nos. C31400, C31600, and C32000 available for general and screw machine applications.

1.2 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. 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.

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.
