Abstract
In material applications in which besides a high wear resistance also excellent corrosion resistance, strength and toughness are required, conventional hard metal alloys have appeared inadequate. According to the invention a hard metal alloy now exists which fulfils these requirements. It is based on WC-Ni, and the binder phase of nickel is alloyed with low, well adjusted concentrations of above all Cr and Mo.
