Tungsten Carbide Seal Faces

6% Ni Tungsten Carbide, 8% Ni Tungsten Carbide, 6% Co Tungsten Carbide, 8% Co Tungsten Carbide, and Light Tungsten Carbide

Tungsten carbide is widely used as seal faces with resistant-wearing, high fractural strength, high thermal conductivity, and small heat expansion co-efficient. Tungsten carbide is the best material to resist heat and fracture in all hard face materials.
