Abstract
The invention provides a process for the manufacture of copper alloys having improved processability. The alloys are melted and atomized into droplets which are spray cast into a coherent deposit. The spray cast alloys are characterized by a finer dispersion of intermetallic than is possible by conventional casting. The alloys are capable of being cold rolled to a reduction of up to 70%. The spray cast alloys exhibit good electrical conductivity and a high yield strength. They are particularly suited for electrical spring contacts.
