One is to improve the quality of cemented carbide.

The second is to improve the bonding strength between the cemented carbide and the matrix (such as changing the gluing method to welding).

The third is to change the strength of the matrix, use tungsten/light carbide particles for surface processing, or add tungsten/light carbide particles when casting the matrix to increase the strength of the matrix. This is also the most direct and effective way to increase the service life of wear-resistant parts and minimize costs.

The following is a performance comparison table of three cemented carbide particle grades:

Usually we will refer to the working conditions used by customers to select the best grade to obtain the longest service life.

For example, when used in crushers, we usually ask customers about the feed size of the crushed materials, the material of the crushed materials, etc… or the area of use.
(For example, the cobblestones in the Jialing River Basin are many times harder than ordinary cobblestones, so the same brand of stone used in the Jialing River Basin will have its service life halved.)

When used on agricultural machinery, we usually ask customers whether the worn contact surface is sand or mud, or other roads that wear out quickly.

Usually we also make distinctions in the size of cemented carbide particles, and the fields of use are also different. The following is a comparison table of our application fields of different particle sizes:

ps: These are just a few representative carbide particle sizes. We can produce more carbide particles of different sizes according to customer requirements.

Rettek is continuously providing more effective wear-resistant solutions to more and more customers, and hopes to meet you on the way forward!
