Anotace textu normy ASTM B768-22 :
This specification establishes the requirements for strips and sheets of copper-cobalt-beryllium and copper-nickel-beryllium alloys with Copper Alloy UNS Nos. C17410, C17450, and C17460. The materials for manufacture shall be cast billets or slabs 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, which shall be rolled to finished size and heat treated when required to meet temper properties. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, length, width, straightness, and edge contours), mechanical (tensile and yield strength, Rockwell hardness, and elongation), electrical conductivity, and chemical composition requirements.
