The wire drawing die industry has experienced decades of development, and many new core materials for wire drawing dies have emerged.

According to the types of materials, the wire drawing dies can be divided into alloy steel dies, tungsten carbide dies, natural diamond dies, polycrystalline diamond dies, CVD diamond dies and ceramic dies.

The development of new materials greatly enriches the application range of the wire drawing die and increases the service life of the wire drawing die.

Comparison of the advantages and disadvantages of various drawing die materials:

Drawing dies material Advantage Disadvantage Application
Alloy steel drawing dies Easy to make Poor wear resistance and short life Basically eliminated
Natural diamond drawing dies (ND Drawing Dies) High hardness and good wear resistance Brittle and difficult to process Used to manufacture wire drawing die cores with a diameter of less than 1.2mm
Tungsten carbide drawing dies (TC Drawing Dies) Good polishability and low energy consumption Poor wear resistance and difficult processing Various diameter wires
Polycrystalline synthetic diamond drawing dies (PCD Drawing Dies) High hardness and good wear resistance Difficulty in processing and high cost Small wire, metal wire
CVD coating material drawing dies (CVD Drawing Dies) High finish, good temperature resistance Complex process, difficult to process
Ceramic material drawing dies Wear resistance, high temperature resistance, good corrosion resistance Thermal shock, poor toughness, difficult processing No large-scale application
