The Influence of Natural Diamond Material Core on the Life of Wire Drawing Die

Natural diamond, commonly known as diamond, is the hardest substance in nature, with high wear resistance and thermal conductivity. When used for drawing tungsten molybdenum wires, it can improve the surface quality of the wire, improve the performance and dimensional accuracy of the wire, and is mainly used for drawing fine and finished wires. But its properties are very brittle, its impact resistance is poor, and its hardness is anisotropic, making it easy to wear unevenly when making wire drawing dies. In addition, diamonds are scarce, expensive, and difficult to process, which limits their ability to draw medium and coarse threads.
