Cemented carbide is a kind of powder metallurgy material, which is formed by mixing metal carbide powder with high melting point and hardness such as WC, T 10 and other binders such as Co and Ni. It is also called cermet cemented carbide because it is similar to the sintering process of ceramics.

Basic introduction Chinese name: Cermet-type cemented carbide alias: Cermet-type cemented carbide performance characteristics: high hardness, high compressive strength, good wear resistance and brittleness. Application field: molds are widely used in molds because of their high hardness, up to 87~9 1HRC, high compressive strength and good wear resistance. The die made of cemented carbide is durable, the service life is 30~ 100 times higher than that of ordinary steel, and the product surface quality is good, which is suitable for mass production. Because the matrix of cemented carbide is hard WC and TiC, it is difficult to process, so the filling cost of cemented carbide is 3~4 times higher than that of steel stamping die, which is not suitable for small batch stamping parts. According to the different kinds of metal carbides, cemented carbides are usually divided into two categories: one is tungsten, cobalt and titanium, and the brand is represented by YT, and the following figures represent the mass fraction of TiC. Cemented carbide is characterized by high hardness, high compressive strength, good wear resistance and brittleness, and cannot be forged and heat treated. It is mainly used for making inserts of multi-station progressive dies and large-diameter drawing dies. Compared with W-Co-Ti cemented carbide, W-Co has better strength and toughness and is widely used in molds.
