Cemented carbide is an extremely hard composite made of equal parts tungsten and carbon. The result is a ceramic type material, sometimes cobalt is added to form an extremely hard metal composite (WC CO)
Tungsten carbide is called a cermet, which is a compound of a ceramic phase (WC) and a binder metal (Co). Tungsten carbide is characterised by a very high hardness and wear resistance. This results in an excellent service life of the components and tools. It is a good electrical and thermal conductor. Due to the magnetic binders (cobalt or nickel), the cermet is also magnetic. Tungsten carbide can be soldered or glued to other components. Screw connections are also possible. The properties of the material depend on the mixing ratio of WC to binder, but also on the particle size of the WC particles. Tungsten Carbide Cobalt can be 3D printed using Binder Jetting technology.
Examples of applications are cutting tools and other wear resistant machine parts and tools such as saw blades, drill bits, bearings, high pressure nozzles, pistons and welding equipment.
