Anotácia textu normy ASTM B465-20 :

This specification establishes the requirements for plates, sheets, strips, and rolled bars of copper-iron alloys with Copper Alloy UNS Nos. C19200, C19210, C19400, C19500, C19700, and C19720. The material for manufacture shall be a cast bar, cake, or slab and so forth 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 shall be available in the following: O60 (soft annealed), O61 (annealed), O50 (light annealed), O82 (annealed to temper, 1/2 hard), H01 (1/4 hard), H02 (1/2 hard), H03 (3/4 hard), H04 (hard), H06 (extra hard), HR02 (1/2 hard), HR04 (hard), H08 (spring), H10 (extra spring), and H14 (super spring). Products shall be tested and shall adhere to dimensional (mass, thickness, length, width, straightness, and edge), mechanical (tensile strength, and Rockwell hardness), electrical (resistivity and equivalent conductivity), chemical composition, and grain size requirements.
