Product Description

(tungsten carbide seal, tc seal, mechanical seal, pump seal, bushing, sleeve pipe, gasket, metal seal) 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. TC physical property Technical Parameter Unit YWN6 YWN8 YG6 YG8 DYNT*0 Composition WC % *4 *2 *4 *2 Ni % 6 8 Co % 6 8 Density g/cm3 *4.***4.9 *4.***4.8 *4.***5 *4.***4.9 6.**6.8 Hardness HRA *8.5 *8 *9.5 *9 *0 Fractural Strength Mpa ***0 ***0 ***1 ***0 ***0 Heat Expansion Co-efficient ***6/K 5.2 5.3 5 5.1 7.5
