(tungsten carbide seal,tc seal,bushing,gasket,rod,ring,etc.seal face,sealing parts,mechanical seal,shaft seal,pump seal)
The Tungsten carbide is the basical material among the frictional materials. It has the advantages of excellent corrosion resistance, high coefficient of heat conductivity, small expansion coefficient, so it is the high characteristics for the various mechanical sealed-in unit.
