ABSTRACT:
A method for the manufacture of a copper based alloy and the alloy produced thereby having improved mechanical properties. An alloy containing a dispersoid ingredient and a precipitating ingredient are spray cast so that during spray casting the dispersoid ingredient forms a second phase as a uniform dispersion of relatively small dispersoids. After solution treating and aging, the solid state precipitating ingredient precipitates as a third phase of a solid state precipitate.
