Carbide is the most widely used class of high-speed machining (HSM) tool materials produced by powder metallurgy processes, consisting of hard carbides (usually tungsten carbide WC) particles and relatively soft metal binders composition. Currently, there are hundreds of different WC-based hard alloy, most of them using cobalt (Co) as a binder, nickel (Ni) and chromium (Cr) is a commonly used binder element, you can also add other Some alloying elements. I produced the carbide has become an ideal tool material.
