The performance of diamond tools metal sintered body is one of the most important factors that affect the cutting performance of the diamond. Therefore, using the suitable processing method to control or adjust the performance of metal sintered body materials plays an important role in stabilizing and improving the diamond tool quality. At present, the main metal sintered materials are made by the simple substance metal powder and copper alloy powder through pressing and sintering after mechanical mixing. The advantages are large adjustment range of component and performance, but there are many influencing factors if using simple substance powder. So it is not easy to control the sintering quality. Pre-alloyed powder is developed just for solve the problem.

Exin Diamond Material is the company that first tried to take the place of simple substance metal powder by prealloy powder to make diamond tools, so it has many rich experiences. The company established a special high-pressure water atomization production line and developed independently the brand of multielement prealloy powder, taking EXD as the representative product depending on absorbing advanced atomization manufacturing process and technology at home and abroad. The prealloy powder produced by the company reduced the cost and the products are alloying, reducing the diamond usage amount and increasing the quality stability of diamond tools. They have many advantages that some other factories don’t have.

1. High-purity raw material and auxiliary material, high-purity powder

2. Special slagging deoxidation processing and low oxygen content

3. Special atomization processing and fine powder

4. Special postprocessing and good powder cold press molding

5. Advanced oxidation treatment method and good powder inoxidizability

6. Strict quality control system and high powder stability

Moreover, it has been the inevitable trend to take the high-quality micro alloyed metal powder by traditional simple substance metal powder as the strong demand of processing material for the diamond performance.
