According to the composition, cemented carbides can be divided into five categories: tungsten carbide based cemented carbides, titanium carbide based cemented carbides, coated cemented carbides, steel based cemented carbides and other cemented carbides.<\/p>\n\n\n\n
According to its application scope, cemented carbide can be divided into four categories: cemented carbide cutting tools, cemented carbide molds, cemented carbide measuring tools and wear-resistant parts, and cemented carbide for mining and petroleum geology.<\/p>\n\n\n\n
Generally speaking, WC Co cemented carbide is widely used in cutting tools, metal drawing dies, stamping dies, measuring tools of cast iron, non-ferrous metals and their alloys, as well as wear-resistant parts for mining machinery and geological exploration; WC Ti Co alloys are mainly used in steel cutting; WC TiC – (NBC) – Co alloys are mainly used for cutting high hardness parts.<\/p>\n\n\n\n
Although other types of cemented carbides have made great progress in recent years and achieved great success in some special applications, WC Co series cemented carbides (i.e. YG type) have excellent comprehensive mechanical properties, which are the most widely used and the largest amount of cemented carbides in industry.<\/p>\n\n\n\n
