This specification establishes the requirements for round, square, and flat phosphor bronze wires of UNS Alloy Nos. C51000, C52100, and C52400 for general and spring applications. The material for manufacture shall be a casting billet of such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Tempers available under this specification are O61 (annealed), H01 (? hard), H02 (? hard), H03 (? hard), H04 (hard), H06 (extra hard), H08 (spring), and H10 (extra spring). Products shall be tested and shall adhere to dimensional (mass, diameter, thickness, length, width, straightness, and edge contours), mechanical (tensile and bending strength, and elongation), and chemical composition requirements.
