Experts tell the quality of tungsten carbide from a uniform particle structure with very minimal inclusions and impurities. Users can tell a good quality product from its durability and pattern of wear.
Porosity says a lot about the raw materials' purity and the care taken in the production process. The greater the tool's porosity, the more it will wear and the greater the risk it will break.
The hardness of sintered tools is determined by the composition of the raw material powder and the size of the particles. If the hardness is matched to the job in hand, then wear is low.
If tools break, it means the tungsten carbide quality is poor or the tool is not designed for the use in question. We avoid this with premium quality and by helping users to choose the right tools.
Tungsten carbide must show great resistance to wear, yet also be sufficiently ductile. Every application requires varying ratios here of hardness and ductile quality. Betek's technical knowledge and great experience make the company leading specialists in this area.
