Cemented carbide is a kind of composite material which is made of refractory metal hard compounds (WC, TiC, etc.) and bonding metals (CO, Ni, Fe, etc.) by powder metallurgy. Cemented carbide has high hardness, high wear resistance, high strength, high modulus of elasticity, low coefficient of thermal expansion, high red hardness and stable chemical properties.

Zhuzhou Sanxin cemented carbide products mainly include nozzles, bushings & sleeves, sealing rings, molds, inserts, mill rollers, and other customized components.
Cemented carbide is a composite hard alloy material that consists of refractory metal bonded together by a metallic binder through powder metallurgy.
High hardness, wear resistance, strength, and toughness are all its exceptional properties to be widely used in industrial parts and tools for most harsh and aggressive environments.
It is generally accepted that tungsten carbide and tungsten alloy best fit the definitions of cemented carbide, which is also well known as the name metal ceramic.
Machining capability of solid tungsten carbide parts:
Maximum Size: Φ85 * 1200mm
Minimum Size: Φ0.045 * 14mm
