Diamond powder is a premium super-hard abrasive material manufactured from LGD (lab-grown diamond). It possesses excellent hardness, strength, toughness, and thermal conductivity, along with outstanding thermal stability and impact resistance. This material is widely used in cutting, grinding, polishing, precision grinding, and ultra-precision finishing processes. It is ideal for processing high-hardness materials such as cemented carbide, metals, non-metals, tungsten steel, ceramics, gemstones, optical glass, quartz, and acrylic. Depending on the application, you can choose between polycrystalline diamond powder and monocrystalline diamond powder.
