SP2000 Tungsten carbide
Tungsten carbide (TC) occupies an important position in the sealing materials, due to its high hardness, rigidity, wearability, good thermal conductivity, and small heat expansion co-efficient.
It is widely used as seal faces, especially suitable in heavy load mediums containing solid particles and which are easy crystallizing.
