Tungsten Carbide

5.5 Tungsten Carbide. Tungsten carbide is cermet, a ceramic crystalline material that is bound together with a metallic binder. In the case of seal rings, this is either cobalt or nickel. Tungsten carbide was the first hard, high-strength and high-conductivity material to be used for seal faces and was quite widely used in the 1960s and 1970s.
