The common cemented carbide always include tungsten cobalt series, with YG as its code name, and tungsten titanium series, with YT as its code name, as usual, because of the good performance of impact resistance for tungsten cobalt series cemented carbide, it is widely used in wooden material cutting, for example, when looking at woodworking cemented carbide cutting tool, you sometimes can find the mark such as YG8 or YG15 on its body, do you know the meaning of this mark? The number behind YG is the content of cobalt contained inside, the more content of cobalt, the better performance of alloy’s impact resistance and bending strength.
