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.
This grade is suitable for semi-finishing to medium roughing over a variety of materials, cast irons, 200, 300 and 400 series stainless steel, carbon steels and high temperature alloys. Excellent life at higher speeds of 500 to 800 SFM with greater resistance to heat and edge wear.
