Non-bond tungsten carbide is a kind of hard alloy product that has no or very small amount of metal bonding agent (mass fraction less than 0.5%). It has unparalleled excellent wear resistance, excellent corrosion resistance, excellent polishing and antioxidant properties.

 

At the same time, as it reduces the use of cobalt and reduces the cost, it has a wide application prospect in the fields of wear-resistant parts, corrosion resistant parts, tools, moulds and so on.

 

 

Advantages of Non-Bond Tungsten Carbide

There are hard and bond phases (Co, Fe, Ni) in tungsten carbide. In a certain harsh environment, these bonds are more easily corroded and oxidized than the hard phase, resulting in a limited application in some fields. It is considered to reduce the content of the bond phase to solve this problem.

 

Cobalt is an expensive material and has a certain impact on human health. It is also necessary to reduce the application of cemented carbide from the perspective of reducing cost and human health.

 

Application of Non-Bond Tungsten Carbide

Compared with the traditional carbide, non-bond tungsten carbide has excellent wear resistance, corrosion resistance, and has a wide application prospect. With its excellent wear resistance and corrosion resistance, it can be used for the manufacture of heavy load sliding seal wear parts of electronic packaging materials. With its excellent cutting performance, it can be used as a tool and bit material, especially for the processing of titanium alloy, and the working efficiency will be greatly improved. Because of its antioxidation and excellent polishing, it can be used as a mold and decorative material.
