ABSTRACT:
A new copper-based metallic alloy is described containing principally Zn and Al in quantities such as to render it capable, after solution heat treatment at high temperature, and tempering, of assuming a crystalline structure of Beta type; its principal characteristics lies in the fact that it simultaneously contains, as grain size reducing additives, Nb and Ti in an overall quantity lying between 0.01 and 0.2% by weight.
