CVD polycrystalline diamond Blanks for Wire Drawing Dies produced by JCB does not contain any additives, is a polycrystalline structure of pure diamond, with high hardness, wear resistance and thermal stability and high wire drawing finish characteristics, comprehensive advantages of PCD polycrystalline wire drawing die core and single crystal diamond die core, can be used for copper, aluminum, stainless steel, tungsten, molybdenum and all kinds of alloy wire drawing. It has more obvious advantages in the high temperature drawing and microwire drawing of tungsten and molybdenum wire, and CVD diamond is non-conductive, and the advantages of making wire core are more prominent, and it is an ideal substitute for natural diamond wire drawing core and imported PCD polycrystalline wire drawing core.
CVD (Chemical Vapor Deposition) diamond is a mixture of carbon-containing gas and hydrogen that is excited to decompose at high temperature and under pressure below standard atmospheric pressure to form active diamond carbon atoms, and deposit interactively growing polycrystalline diamond on the matrix. Because CVD diamond does not contain any metal catalyst, its thermal stability is close to that of natural diamond. The CVD diamond grains are disordered and have no brittle cleavage plane, so they are isotropic. CVD diamond is widely used in machinery, microelectronics, thermal, optics, aerospace, military, medical and other fields. Our company mainly produces the following types of CVD polycrystalline diamond products: CVD polycrystalline diamond wire drawing die core, CVD polycrystalline diamond dresser blank, CVD polycrystalline diamond tool blank, thermal grade CVD polycrystalline diamond sheet, optical grade CVD polycrystalline diamond sheet and other multi-grade CVD products. And according to user requirements for cutting, polishing and other processing.
