Cemented carbides are a class of hard materials used extensively for cutting tools, as well as in other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of "carbide" or "tungsten carbide" in industrial contexts usually refer to these cemented composites. The cobalt content could vary from 5% to 23% base on application. 8% to 12% are the most common for cutting tools. Ruthenium is used to replace cobalt as a perfered binder for the best cutting performance.
Polycrystalline, carbide reinforced diamond on medium grain carbide pad. G ood cutting edge sharpness and low cutting forces allow small tolerance machining. Increased wear resistance and toughness. Finishing and general purpose machining of all non-ferrous metals at high cutting speeds.
