The company's oil-based diamond composite sheet introduced US technology, using a higher level of diamond powder and cemented carbide substrate, using new high-efficiency catalysts and new processes, with a complete CC bond between the diamond grains in the polycrystalline diamond layer. The microscopic characteristics of the bond enable the diamond layer to have high strength, high hardness and high wear resistance. Using a variety of tooth structure and special post-processing technology, effectively reduce the residual stress of the diamond composite sheet, the interface is more solid and uniform, with high thermal stability and strong impact toughness.
