At JLS Precision, the carbide grades of CB-Ceratizit we mainly use are WF15, WF20, WF30, KG3, KG7, WF25, NA10, etc. They are of excellent wear resistance, good corrosion, and good impact resistance. The service life of tooling components, such as tungsten carbide punch and die, are extremely extended.
Tungsten carbide is one of the hardest and most wear-resistant materials available. It is often used for die components in high-volume manufacturing situations. It is also used for machine parts that come in contact with very abrasive materials.
Tungsten carbide is a combination of tungsten carbide powder and a binder metal, such as cobalt or nickel, which holds the tungsten carbide powder together. By adjusting the percentage of binder metal, tungsten carbide components can be made very wear-resistant but brittle or very durable but not as wear-resistant.
Hard metal, or tungsten carbide, thanks to its characteristics of very high quality, resistance to wear, and hardness, is used for the production of special anti-wear tools, punches, and dies for blanking dies that must produce millions of metal parts, ranging mainly in the various sectors aeronautics, aerospace, petrochemical, food, automotive, medical, naval, energy, electrical, mechanical and household appliances.
