Tungsten Carbide is often referred to as a Hard Metal due to it’s very high hardness
in relation to other metals. Typically a Tungsten Carbide Hard Metal can have a hardness value of 1600 HV,
whereas mild steel would be in the region of 160 HV a factor of 10 lower. Although called a hard metal,
Tungsten Carbide is actually a composite material with hard particles of Tungsten Carbide embedded
in a softer matrix of metallic Cobalt.
Tungsten Carbide 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.
