Cemented Carbide

Cemented Carbide is a kind of powder metallurgy product, which is mainly composed of high hardness refractory metal carbide micro powder and sintered in vacuum sintering furnace or HIP sintering furnace. The metal element cobalt , nickel , molybdenum  are used as binder.

Within the field of engineering materials, tungsten carbides play a crucial role as they combine high hardness and high toughness, and they constitute the most versatile hard materials group for engineering and tooling applications.

Advantages of Cemented Carbide

Does not wear so quickly as it is harder
Resists even high temperatures
Application fields: wherever tools or components are exposed to high wear (e.g. when cutting hard materials)
Improved quality of the tools and parts
Longer tool life
Improved security


Cemented Carbide in Comparison to Other Materials

Diamond/PCD: hardest existing material, but characterised by high fracture toughness
Cemented carbide: enormous flexibility thanks to composition, can be designed either with higher toughness or higher wear resistance depending on the application. Range of applications varies extremely for cemented carbide and offers the greatest scope
Steel: high toughness, but low hardness
Ceramic: very low density, lighter than cemented carbide and heat-conducting, excellent hardness, low toughness
CBN: high hardness, low toughness
Cermet: high hardness, combines the hardness of cemented carbide and ceramic, but less tough.
