process for the production of a cu - zn al6 formgedu00e4chtnislegierung with low martensitischer transformation

摘要

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 DEG C to 30 DEG C i.e. a lowering of 80 DEG C wherein previously high temperature betatised material has been subjected to re-betatising at lower temperature in order to utilize the material suitably.
