Anotation

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.
