Cemented carbide is a high hardness, high strength, high wear resistance metal material, mainly composed of tungsten and cobalt.
But in order to further improve a certain property other trace elements are added.
For example: nickel, chromium, titanium, niobium, vanadium, zirconium, etc. Chromium improves the wear resistance and corrosion resistance of cemented carbide. Titanium, niobium, vanadium and other elements can improve the hardness and wear resistance of cemented carbide, and nickel can improve its corrosion resistance and heat resistance.
In conclusion, the addition of trace elements can further improve the performance of cemented carbide. Different trace elements have different effects on the performance and need to be selected according to the specific application.
