275 ABSTRACT OF THE INVENTION This invention is directed to age hardenable copper beryllium alloys, and to articles and parts made therefrom, which contain special small amounts of beryllium and cobalt; e.g., about 0.2% to about 0.5% beryllium and about 0.2% to about 0.4% cobalt, which, when finished by solution treating, cold working at least about 50% or at least about 70% and age hardening have a superior combination of stress relaxation resistance, formability, ductility, conductivity and strength.
