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.
We can do stamping,processing,mold making,spark-erosion wire cutting,etc.
