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.
1st choice in grey cast iron. When the highest productivity is required. Highest wear resistance in continuous cuts of all cast irons. Higher speed and easier cast iron applications than TK1501. Using MR9 creates a very secure, high productivity solution. Highest performance even in hardened steels.
