The tungsten metal powder can be converted to tungsten carbide (WC) by reaction with pure carbon powder, e.g. carbon black, at 900 - 2200 C in pusher or batch furnaces. Tungsten carbide behaves similarly to unalloyed tungsten and is resistant to chemical attack, although it reacts strongly with chlorine to form tungsten hexachloride.
Mill Products. Just over 10% of tungsten carbide is used exclusively for the manufacture of mill products including various end mills and mill inserts. These products vary in size and shape depending on the material they will be coming in contact with, but all are used for applications in grinding and milling.
