Tungsten carbide seal
Tungsten Carbide Seal ring is one of the most widely-used hard surface materials among mechanical seal friction material. Because it’s good wearable resistance, great anti-bend strength, high thermal conductivity, small co-efficient of expansion, it has a very wide range of application. It also has the highest co-efficient of heat shock among all the hard surface material.
