ABSTRACT:
A wire having a tensile strength of at least 95 psi and conductivity of at least 60 percent IACS is provided. The wire is manufactured from a precipitation hardenable alloy, the alloy consisting essentially of about 0.38 percent beryllium, 1.66 percent nickel or cobalt and the remainder copper. The manufacture comprises one or more processing steps concluding with cold working the alloy to a wire and an area reduction of at least 99 percent.
