Anotácia

This specification establishes the requirements for copper-beryllium alloy (Copper Alloy UNS Nos. C17200 and C173002) wires in coils, spools, or other forms except straight lengths, of any uniform cross section. Products shall be available in the following tempers: solution heat-treated TB00, and cold-worked TD00 to TD04, which shall be precipitation heat treated after forming. Products that are already precipitation heat treated by the manufacturer shall be available in tempers TF00 (AT), and TH01 to TH04. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (diameter, thickness, length, width, and straightness), mechanical (tensile and bend strength, Rockwell hardness, and elongation), physical (grain size and count), and chemical composition requirements.
