Tungsten Carbide TC
Tungsten Carbide TC
Tungsten carbide is one of the hardest ceramics currently known (HRC is about 90 units) — it is comparable to diamond in hardness. In addition to hardness, tungsten carbide has a high melting point, wear resistance, good oxidation resistance. We use tungsten carbide with a bunch of cobalt or nickel in our production.
Tungsten carbide with a cobalt bond (U1) is used in environments with a high content of abrasive particles, as well as at high pressures and temperatures, but it is unsuitable for food media (dissolves even in distilled water), and for nuclear power.
Tungsten carbide with a nickel binder (U2) is used in concentrated solutions of alkalis, including artesian, technical and wastewater, as well as used in food industry environments.
