Abstract: A process for producing a copper beryllium alloy. The process includes the steps of: preparing a copper beryllium melt; casting the melt; hot working the cast copper beryllium; annealing the copper beryllium; cold working the annealed copper beryllium; and hardening the copper beryllium; and is characterized by the improvement comprising the steps of: solution annealing the cold worked copper beryllium at a temperature of from 1275.degree. (691.degree.) to 1375.degree. F. (746.degree. C.); hardening the annealed copper beryllium at a temperature of from 400.degree. (204.degree.) to 580.degree. F. (304.degree. C.); cold rolling the hardened copper beryllium; and stress relief annealing the cold worked copper beryllium at a temperature of from 400.degree. (204.degree.) to 700.degree. F. (371.degree. C.).An alloy consisting essentially of, in weight percent, from 0.4 to 2.5% beryllium, up to 3.5% of material from the group consisting of cobalt and nickel, up to 0.

Abstract: A process for producing formed copper beryllium alloys. The process includes the steps of: preparing a copper beryllium melt; casting the melt; hot working the cast copper beryllium; solution annealing the copper beryllium; optionally cold working the solution annealed copper beryllium; forming the copper beryllium; and age hardening the formed copper beryllium; and the improvement comprising the step of preaging the solution annealed or solution annealed and cold worked copper beryllium, prior to forming, at a temperature of from 400.degree. to 1000.degree. F. for a period of up to 180 seconds, the copper beryllium being at final gauge prior to preaging.
