Carbide production / blanks<br />
Carbide is a composite material consisting of particles mainly with tungsten carbide as hard material<br />
and a metallic binder. For this reason, with carbide it is possible to achieve hardness and toughness<br />
combinations which cannot be obtained with other materials. The graphic illustration below shows the<br />
basic steps for producing carbide blanks in the metal forming sector.<br />
Powder preparation<br />
Due to its high melting point tungsten carbide (WC) can only be produced through sintering when needed<br />
for technically sophisticated applications. For this purpose, the powder consisting of the tungsten carbide,<br />
the cobalt binder (Co) and sometimes additional alloys, is mixed, milled and spray-dried.<br />
This process results in a spray-dried granulate which can easily be used for production, since its chemical<br />
and physical properties have already been adapted to the final carbide specification (e.g. WC grain<br />
size).<br />
