CVD Diamond wire drawing die core

Introduction：

CVD (Chemical Vapor Deposition) Diamond is a mixture of carbon-containing gas and hydrogen at high temperatures and sub-standard atmospheric pressure is excited to decompose to form an active Diamond carbon atoms and deposited on the substrate intergrowth of polycrystalline Diamond.Since CVD Diamond does not contain any metal catalyst, so its thermal stability close to natural Diamond.CVD Diamond grains are disordered, non-brittle cleavage plane, thus showing isotropic.CVD Diamond is widely used in mechanical, microelectronics, thermal, optical, Aerospace, Military, Medical and other fields.Our company mainly produces the following types of CVD Diamond products: CVD Diamond wire drawing die core, CVD Diamond dresser blank, CVD Diamond cutter blank, thermal grade CVD Diamond sheet, optical grade CVD Diamond sheet and other multi-grade CVD products.And can be cut according to user requirements, polishing and other processing

Product introduction：

The CVD Diamond wire drawing die core produced by our company contains no additives, is a pure Diamond of polycrystalline structure, has the characteristics of high hardness, wear resistance and thermal stability and drawing smooth finish，It can be used for drawing copper, aluminum, stainless steel, tungsten, molybdenum and all kinds of alloy wire, and it has obvious advantages in high-temperature drawing and micro-wire drawing of tungsten and molybdenum wire.
