Cemented Carbide

① Excellent Material Properties
Cemented carbide is a high-performance material primarily composed of tungsten carbide (WC) and a metallic binder such as cobalt (Co). It offers extremely high hardness, compressive strength, and wear resistance while maintaining better toughness than most ceramics. Its excellent resistance to wear makes it ideal for components that require long service life and stable dimensional accuracy.

② Advantages over Metals
Compared with conventional steels, cemented carbide provides significantly higher hardness and wear resistance, helping to minimize wear caused by cutting, sliding, and repeated contact. In applications such as cutting tools, dies, molds, and wear-resistant components, it can extend component life and reduce replacement and maintenance frequency. However, because its toughness is generally lower than that of steel, selecting the appropriate grade according to the application is essential.

③ Advantages over Ceramics
Compared with ceramics, cemented carbide generally offers higher toughness due to its metallic binder phase, making it more suitable for applications involving impact and repeated mechanical loads. It provides an excellent balance of high hardness, wear resistance, strength, and toughness, while reducing the risk of chipping or fracture compared with many ceramic materials.

④ Typical Applications
Cemented carbide is widely used for cutting tools, molds, punches and dies, precision machine components, guides, nozzles, rollers, sliding components, and wear-resistant jigs. It is particularly effective in applications where minimizing wear and maintaining dimensional accuracy over a long period are critical.

⑤ Why Choose Cemented Carbide?
The greatest advantage of cemented carbide is its ability to combine extremely high hardness and wear resistance with excellent mechanical strength and toughness. By reducing dimensional changes caused by wear, cemented carbide can extend component life, reduce maintenance and replacement costs, and contribute to stable equipment operation and higher productivity.
