ASTM B371/B371M-19(2026)

Annotation of standard text ASTM B371/B371M-19(2026) :

This specification establishes the requirements for rods of copper-zinc-silicon alloy with Copper Alloy UNS Nos. C69300, C69400, C69430, C69700, and C69710. The materials for manufacture shall be cast billets, logs, or rods of such purity and soundness as to be suitable for processing by cold working, annealing, straightening, and cutting to length as may be necessary to produce finished products that meet the properties specified. Tempers available under this specification are H02 (half hard) for UNS No. C69300, and H04 (hard) for all other UNS Nos. Products shall be tested (including by residual stress test and ammonia vapor test) and shall adhere to dimensional (diameter, length, straightness, and edge contour), mechanical (tensile and yield strength, and elongation), and chemical composition requirements.
