Abstract:
An electrical device having a spring section capable of maintaining a desired spring normal force after repeated matings and a crimp section capable of being joined to a wire or other component by crack-free crimping without localized annealing of the crimp section before crimping, the device being formed from an alloy comprising 0.15 to 0.5 wt. % Be, 0.4 to 1.40 wt. % Ni or Co or both, 0.2 to 1.0 wt. % Pb, up to 0.50 wt. % Zn, the balance being copper and incidental impurities, wherein the device after final solution annealing is cold worked by 40 to 80% and is overaged during age-hardening so that the alloy forming the device achieves a final 0.2% yield strength between about 60 and 80 ksi.
