ABSTRACT:
There is disclosed a cemented carbide tool containing tungsten carbide, titanium carbide, nickel and cobalt, molybdenum and chromium. The composition of the materials provides a good resistance to corrosion as well as high hardness and wear resistance. These properties are particularly interesting for the manufacture of tools for coldforming operations. Cold forming tools made with these materials have steady performance over a long period of time.
