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 materialAdvantageDisadvantageApplication
Alloy steel drawing diesEasy to makePoor wear resistance and short lifeBasically eliminated
Natural diamond drawing dies (ND Drawing Dies)High hardness and good wear resistanceBrittle and difficult to processUsed 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 consumptionPoor wear resistance and difficult processingVarious diameter wires
Polycrystalline synthetic diamond drawing dies (PCD Drawing Dies)High hardness and good wear resistanceDifficulty in processing and high costSmall wire, metal wire
CVD coating material drawing dies (CVD Drawing Dies)High finish, good temperature resistanceComplex process, difficult to process
Ceramic material drawing diesWear resistance, high temperature resistance, good corrosion resistanceThermal shock, poor toughness, difficult processingNo large-scale application
