The CVD polycrystalline diamond Blanks for Wire Drawing Dies produced by JCB contain no additives and are composed of pure diamond with a polycrystalline structure. They exhibit extremely high hardness, wear resistance, thermal stability, and excellent wire drawing surface finish. Combining the advantages of PCD polycrystalline wire drawing die cores and single crystal diamond die cores, they are suitable for drawing copper, aluminum, stainless steel, tungsten, molybdenum, and various alloy wires. They offer significant advantages in high-temperature drawing of tungsten and molybdenum wires and micro-wire drawing. Additionally, CVD diamond is non-conductive, making it particularly advantageous for producing wire drawing die cores. It serves as an ideal replacement for natural diamond wire drawing die cores and imported CVD polycrystalline diamond Blanks for Wire Drawing Dies
Polycrystalline Diamond wire drawing core 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 PCD polycrystalline wire drawing core and single crystal diamond core advantages, can be used for copper, aluminum, stainless steel, tungsten, molybdenum and all kinds of alloy wire drawing. Has more obvious advantages in high temperature drawing and microfilament drawing of tungsten and molybdenum wire, and CVD Polycrystalline Diamond does not conduct electricity, 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.
