ABSTRACT:
This invention is directed to the treatment of copper beryllium alloys, and to articles and parts made therefrom, containing special small amounts of beryllium and cobalt, e.g., about 0.05% to about 0.5% beryllium and about 0.05% to about 2% cobalt, which imparts to these alloys a superior combination of stress relaxation resistance, formability, ductility, conductivity and strength by the process of solution annealing, cold working at least about 50% or at least about 70% or 90% or more and age hardening.
