ball mill for hard materials

What is Tungsten Carbide or Hard Metal?

2-8-2009How is Hard Metal or Tungsten Carbide Made? Tungsten Carbide Hard Metals are primarily produced using a Powder Metallurgy process, whereby the powdered forms of tungsten carbide and cobalt are mixed using ball mills, a binder material is added to hold the powders together during the next stage of the process which is compaction or pressing.
