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