ABSTRACT:
A dispersion-strengthened copper alloy is disclosed having an exceptional combination of strength, ductility, and thermal conductivity. The copper alloy comprises: copper, 0.01 to 2.0 weight % boron and 0.1 to 6.0 weight % cobalt, and cobalt-boride disperoids that range in size between 0.025 and 0.25 microns in diameter. A copper alloy is made by rapid solidification of the melt into a powder. Strong, thermally conductive articles can be made by compacting the powder at temperatures below the melting temperature of the copper alloy.
