Commonly used metal carbides are tungsten carbide, titanium carbide, niobium carbide and vanadium carbide, etc., which can make cemented carbide have high hardness and high wear resistance. The cemented carbide binder is mainly metal cobalt or metal nickel, etc., which can ensure that the cemented carbide has a certain strength and toughness.
The main alloy components of cemented carbide sheets are WC and Co. The contents of WC and Co in cemented carbide sheets for different purposes are not consistent, and they are widely used.
