PCT No. PCT/SE80/00141 Sec. 371 Date Jan. 15, 1981 Sec. 102(e) Date Jan. 15, 1981 PCT Filed May 14, 1980 PCT Pub. No. WO80/02569 PCT Pub. Date Nov. 27, 1980.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.
