CARBIDE.DEFINITION ANDCOMPOSITION.
The term “carbide” describes materials distinguished by HIGH HARDNESS and special metallurgic properties. To be exact, they are sintered materials consisting mainly of tungsten carbide and a binding agent.
Hard materials are usually Wolfram (WC), Titanium (TiC), Tantalum (TaC), Chromium (CrC) and other carbides. As binding agents Cobalt (Co), Nickel (Ni), Iron (Fe) and Nickel-Chromium (NiCr) are most frequently used. The most common carbide combination is tungsten carbide and Cobalt (WC + Co).
Various carbide composition options cover a
broad spectrum of hardness and possible applications.
CARBIDE:WHAT DETERMINES ITS FEATURES?
The amount of binding agent and grain size of the carbide determines its specific carbide properties. A high amount of binding agent promotes toughness, while a lower amount increases wear resistance. The selection of grain size on the other hand promotes hardness.
THE FINER THE GRAIN, THE HARDER THE MATERIAL.
THE COARSER THE GRAIN, THE BETTER THE MATERIAL’S FRACTURE RESISTANCE.

Our work begins well before sintering. Processing is optimized right from the start, rendering DURIT blanks closer to the end product. They have very low grinding excess and subsequent finishing follows on CNC-sanders and erosion machines. DIN ISO 9001:2015 certified processes ensure a consistently high product quality. Additionally, we comply with the requirements of ISO 14001 and ISO 50001 certifications for effective environmental management and advanced energy management systems.
