Comparison of advantages and disadvantages of several drawing die materials

- Jun 03, 2019-

Drawing die material - advantages - disadvantages - application range

Alloy steel mold - easy to make - poor wear resistance, short life - basic elimination

Natural diamond - high hardness, good wear resistance - large brittleness, difficult to process - wire die with a diameter of 1.2mm or less

Cemented carbide - good polishing, low energy consumption - poor wear resistance, difficult processing - various diameter wire

Polycrystalline synthetic diamond - high hardness, good wear resistance - difficult processing, high cost - small wire, wire

CVD coating material - high finish, good temperature resistance - complex process, difficult processing - small wire, wire

Ceramic materials - good wear resistance, high temperature resistance, good corrosion resistance - thermal shock, poor toughness, difficult processing - no wide range of applications
