ABSTRACT OF THE INVENTION 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.
