Cemented carbide is a composite, the main components of which consists of the powder of refractory carbide like tungsten carbide, titanium carbide through the binder metal powder such as cobalt, nickel, etc. It is a cemented composite obtained through the powder metallurgical method. It is mainly used to make high-speed cutting tools for hard, tough materials, cold working dies, measuring tools, high resistant parts with high stability and free from vibration.
The hardness of the cemented carbide at normal temperature can reach HRA of 86 to 93, equivalent to HRC of 69 to 81. High hardness can be maintained at 900 to 1000 ° C with excellent wear resistance. Compared to high-speed steel, the cutting speed can be 4 to 7 times higher with 5 to 80 times longer life. The hard material of 50 HRC can be cut through carbide products.
In addition to the high hardness, wear-resistance cemented carbide has a series of high performance such as good toughness, heat resistance, high corrosion resistance, high elastic modulus, etc, which can be widely used as cutting tool materials, such as turning tool, milling cutter, planner tool, drill bit, etc., suitable for cutting cast iron, non-ferrous metals, plastic, chemical fiber, graphite, glass, stone, ordinary steel, heat-resistant steel, stainless steel, high manganese steel, tool steel and other much more difficult materials. Tungsten carbide wear parts, mechanical parts and carbide wire drawing dies have advantages of high resistance of high-temperature, friction, corrosion. In various industrial applications, tungsten carbide is an ideal choice for replacing steel.
