Efficient based on continuous improvement of professional work PCD consists of 99.9% carbon isotope C12. Its high thermal conductivity is 50% better than natural diamond and 2 times faster than copper. PCD property provides wear resistance up to 500 times that of conventional carbide. Polycrystalline diamond can be sintered to cemented carbide substrate through special high temperature and pressure process. PCD insert is the best for machining non-ferrous metals and non-metal. It has replaced tungsten carbide and ceramics in a range of high speed performance applications including the turning, boring, milling, slotting and chamfering of materials such as high-silicon aluminum, metal matrix composites (MMC), ceramics, reinforced epoxies, plastics, carbon-fibre-reinforced plastics (CFRP) and engineered wood products. The extended tool life and increased productivity provide by PCD tools offer cost effective solutions for many applications.
