What is the Tungsten carbide?

 

Tungsten carbide is the hardest material on earth, and it is widely used in industrial fields.

 Tungsten carbide is called cemented carbide, it is an alloy material made of refractory carbide (WC) and binder metals by powder metallurgy. Normally the binder is Cobalt or Nickel. The WC powder are mixed with binder Co or Ni, compacted in a mold and then sintered in a vacuum furnace at temperatures no less than 1300°C
