How is cemented carbide made?
A powder metallurgic material
The manufacturing process begins with the composition of a specific cemented carbide powder mixture - tailored for the application.
The cemented carbide powder is compacted into a form. In a high-temperature sintering furnace, the tungsten carbide structure of the blank is shaped at precise temperatures for strictly defined periods. During this heat treatment, the tungsten carbide blank undergoes shrinkage of some 50% in volume.
The sintered Cemented Carbide component gains its final finish by additional grinding, lapping and/or polishing process.
