ABSTRACT:
The present invention provides for Cu—Zn—Al(6%) alloy and an improved process to lower the martensitic transformation temperature, by a low temperature re-betatising treatment from 110° C. to 30° C. i.e. a lowering of 80° C. wherein previously high temperature betatised material has been subjected to re-betatising at lower temperature in order to utilize the material suitably.
