Raw materials. Tungsten carbide is produced from wolfram carbide and cobalt. Wolfram carbide is one of the hardest known materials, but is also brittle. Combining it with weak cobalt a material is generated which is very hard and resistant to wear, and which can withstand extreme impact loads. Top quality. We use only first-class raw materials with hardly any impurities in order to guarantee the best sintering ability. We purchase most of our wolfram carbide and cobalt from Europe. These expensive, but high-quality materials form the basis for the top-class quality of our tools. We do not use recycled goods for reasons of quality. Extensive. The quality of the tungsten carbide is always tailored to the application. This ensures the necessary toughness with good resistance to wear. The most important hard-metal qualities can be found in our grade overview.
