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.
World's thickest Al2O3 layer provides wear resistance greater than a ceramic insert. MC5005 should be applied when machining cast irons at high cutting speeds. Features new substrate and Mitsubishi's TOUGH-GRIP adhesion layer. The newly developed TOUGH-GRIP interlayer takes advantage of a controlled crystalline, nano-scale, structure to prevent spalling of the Al2O3 layer. The Nano-Texture coating has an extremely fine structure which provides superior wear resistance when machining cast iron. New chipbreakers balance cutting efficiency and edge toughness for greater productivity.
