[Know Tungsten] Special Applications of Tungsten: Satellites and Superalloys

Stellites

Cobalt-chromium-tungsten alloys (also Mo, Ni, Fe, C, Si and B can also be used), frequently called stellites, are a group of wear and corrosion resistant alloys which are used for bearings, valve seats and pistons, mill inliners, and applications where a tough wear resistant material is required. They are applied either by hard facing as welding electrodes or powder spraying, or as massive forms produced by casting.
