Carbide is an iron-free sintered material consisting of carbides (titanium carbide, tantalum carbide, molybdenum carbide, vanadium carbide) and binder phase (cobalt).
Cutting speeds of up to approx. 300 m/min can be achieved with carbides. They have a temperature resistance up to 1000°C.
There are three groups of carbides:
Group P carbides have a high heat resistance with low abrasion. They are suitable for long chipping materials
Group M carbides have universal properties
Group K carbides have lower heat resistance, high abrasion resistance and increased toughness. They are suitable for short-chipping materials
Carbides are indicated by a code number. The higher this is, the higher is the toughness. A higher index also means lower wear resistance.
The properties can be further improved by single-layer or multi-layer coatings of ceramic, titanium carbide, titanium nitride or titanium carbonitride.
