  • Processing for copper beryllium alloys
    Patent number: 4394185
    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.
