ABSTRACT:
A process for producing the beryllium-copper alloy comprises the steps of casing a beryllium-copper alloy composed essentially of 1.00 to 2.00% by weight of Be, 0.18 to 0.35% by weight of Co, and the balance being Cu, rolling the cast beryllium-copper alloy, annealing the alloy at 500.degree. to 800.degree. C. for 2 to 10 hours, then cold rolling the annealed alloy at a reduction rate of not less than 40%, annealing the cold rolled alloy again at 500.degree. to 800.degree. C. for 2 to 10 hours, thereafter cold rolling the alloy to a desired thickness, and subjecting the annealed alloy to a final solid solution treatment. The beryllium-copper alloy obtained by this producing process is also disclosed, in which an average grain size is not more than 20 .mu.m, and a natural logarithm of a coefficient of variation of the grain size is not more than 0.25.
