ABSTRACT:
A process for manufacturing a boride dispersion copper alloy by preparing a metallic material having a surface portion comprising at least one of beryllium, gallium, manganese, nickel, palladium, silicon and vanadium, and copper or an alloy thereof, and diffusing boron into the surface portion. The resulting material includes fine boride particles uniformly dispersed in the surface portion and is useful as a material for electrical contacts or sliding parts due to its high resistance to adhesion, wear and arc, and excellent electrical conductivity and sliding properties.
