Ultrafine/Nano Cemented Carbide

Nano cemented carbide which means the WC grain size is less than 0.2μm cemented carbide has higher hardness and strength than normal cemented carbide. At the same time , it can effectively solve the high-speed cutting problems of the difficult-to-cut materials such as superalloy, titanium alloy, composite material, hardened steel, etc., greatly improves machining efficiency, and is the preferred tools material in aerospace field and high-end equipment manufacturing industry.
