Tungsten Carbide

Cemented tungsten carbide is a sintered material mainly consisting of tungsten carbide and a binding agent.

Manufacturing:

SAPEG have an in-house manufacturing line for production of cemented tungsten carbide components (also known as hardmetall). Both traditional serial production with larger series, but also small and medium series and prototypes.

It’s the mix that matters:
The binder content and the grain size determines the mechanical properties of tungsten carbide. A high binder content increases toughness. A low binder content increases hardness and wear resistance. The choice of grain size also affects the hardness. The finer the grain, the harder the material. The coarser the grain, the higher the fracture toughness.

SAPEG use tungsten carbide together with different cobalt content to give the mechanical properties needed for the product’s area of application. Our products typically combine cemented carbide with machined steel parts, joined through brazing. This is to achieve a good combination of wear resistance and toughness in a cost-effective way.
