Although wire drawing dies can be used to process a variety of metal and alloy materials such as steel, copper, tungsten, molybdenum, etc., wire drawing dies of different materials have their own applicable processing ranges. Therefore, a reasonable selection of the material of the wire drawing dies is the key to ensuring successful application. Longest tool life. Wire drawing dies of different materials have their relatively reasonable processing objects.
　　 Wire drawing dies can be divided into alloy steel dies, cemented carbide dies, natural diamond dies, polycrystalline wire drawing dies, diamond dies, CVD diamond dies and ceramic dies according to the material. It is widely used in high-tech industries such as electronic devices, radar, television, instrumentation and aerospace. It has strong wear resistance and extremely long service life.
For example, when drawing copper wires of the same diameter, the service life of the polycrystalline diamond die is 300 to 500 times that of the cemented carbide die, and it is only 80 to 100 times when drawing nickel wires. When drawing molybdenum wires, the service life The service life is only 50 to 80 times that of the cemented carbide die, and when drawing carbon steel, the life of the polycrystalline diamond die is only 20 to 60 times that of the cemented carbide die.
