COPPER BERYLLIUM ALLOY AND THE MANUFACTURE THEREOF ABSTRACT OF THE DISCLOSURE 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 tem- perature of from 1275 (691) to 1375°F (746°C); hardening the annealed copper beryllium at a temperature of from 400 (204) to 580°F (304°C); cold rolling the hardened copper beryllium; and stress relief annealing the cold worked copper beryllium at a temperature of from 400 (204) to 700°F (371°C). An alloy consisting essentially of, in weight percent, from .4 to 2.5% beryllium, up to 3.5% of material from the group consisitng of cobalt and nickel, up to 0.5% of material from the group consisting of titanium and zirconium, up to 0.3% iron, up to 0.7% silicon, up to 0.3% aluminum, up to 1.0% tin, up to 3.0% zinc, up to 1.0% lead, balance essentially copper. The alloy is characterized by equiaxed grains. The grains have an average grain size of less than 9 microns. Substantially all of the grains are less than 12 microns in size.
