Our Cemented Carbide Grades
The quality of tungsten carbide is determined by the quality of the starting powders. This is why AFC Hartmetall works closely with our powder suppliers to ensure they are the highest quality and tailor-made for our products.
Because tungsten carbide is a composite material made of several components, the possibilities for producing different carbides are almost limitless. You can vary:
- the proportion of tungsten carbide (WC) and cobalt (Co)
- the initial grain sizes of the powders used
- different additives to limit grain growth and to improve service life.
AFC Hartmetall produces premium cemented carbides and can tailor a grade for your need.
In order to produce a carbide that meets your requirements, we have options for influencing its properties:
We can vary the grain size of the tungsten carbide starting powder and vary the tungsten carbide / cobalt ratio.
As the grain becomes finener, the hardness and flexural strength increases but the toughness decreases.
As the cobalt content in the cemented carbide increases, the toughness and flexural strength increase but the hardness decreases.
We would be happy to advise you on the selection of the best carbide for your needs.
