Characteristics of Tungsten Carbide

There are two grades of cemented carbide, tungsten carbide and tungsten steel.

One is pure carbide and anti hole types. Pure carbide contains carbides and cobalt only, with best strength and anti-wear characteristics, and its strength and abrasion resistance will be reduced by adding any other substances, it is usually used for cutting cast iron and non-ferrous metal materials.

But the pure carbide cannot endure high temperature, its scrap will stick on the cutter blade face easily during high heat, which causes the flank depression by its diffusion. Carbide added tantalum carbide and titanium carbide is with high temperature resistance because these two ingredients are with higher melting point than tungsten carbide, relatively its strength and anti-ear characteristics are lower than pure carbide.
