Abstract
Copper based alloys, e.g. CuNiSnSi are processed by annealing followed by a high level of cold work area reduction then a recrystallization step which is followed by a low level of cold work prior to spinodal aging. The resultant material is isotropically formable while maintaining high yield strength.
