This specification covers the requirements for plates, sheets, strips, and rolled bars of copper-zinc-tin and copper-zinc-tin-iron-nickel alloys with Copper Alloy UNS Nos. C40500, C40810, C40850, C40860, C41100, C41300, C41500, C42200, C42500, C42520, C43000, and C43400. Materials shall be processed by hot working, cold working, and annealing as to produce a uniform wrought structure in the finished product. Tempers shall be available in the rolled, as hot rolled, or annealed conditions. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, length, width, mass, straightness, and edges), mechanical (tensile strength, and Rockwell hardness), chemical composition, and grain size requirements.
