Natural wire drawing die
Natural diamond wire drawing dies are the most expensive and extremely difficult to process. At the same time, because of the anisotropy of natural diamond, the hardness varies greatly in the radial range, and it is easy to produce severe wear in a certain direction. Therefore, the natural diamond die is only suitable for processing. A wire with a small diameter.
Natural diamond is an allotrope of carbon. The mold made with it has the characteristics of high hardness and good wear resistance. However, natural diamond is more brittle and difficult to process, and is generally used for the manufacture of wire drawing dies having a diameter of 1.2 mm or less. In addition, natural diamonds are expensive and supply is scarce, so natural diamond molds are not the economical and practical drawing tools that people ultimately seek.
