Characteristics and application of tungsten carbide

Characteristics and application of tungsten carbide : Carbide with high hardness and melting point of cemented carbide chambers, powder metallurgy products sintered by using Co.Mo.Ni as a binder. Its room temperature hardness can reach 78-82HRC, it can withstand the high temperature of 850-1000°C, and the cutting speed is 4-10 times higher than that of high-speed steel. However, its impact toughness and flexural strength are far worse than high-speed steel, so it is rarely made into a monolithic tool. . Tungsten carbide is a raw material of the hard alloy family. Pure carbide is not commonly used. It is a black hexagonal crystal with a metallic luster. Its hardness is similar to that of diamond. It is a good conductor for electricity and heat. The melting point is 2870 ° C, the boiling point is 6000 ° C, and the relative density. 15.63 (18 ° C) tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and is easily soluble in a mixed acid of nitric acid-hydrofluoric acid. Pure carbides are brittle, and if a small amount of metal such as titanium or cobalt is added, it can be reduced.
