The Description of PCD Cobalt-Based Drawing Dies

Polycrystalline diamonds are made of diamond micro-powder and metal catalysts in high-temperature and high-pressure environments. They have excellent wear resistance and high hardness. Based on different binders, PCD drawing die cores can be divided into cobalt-based and silicon-based.

Cobalt-based PCD drawing die blanks have metal bonding agents and good machining performance. They can be processed by EDM, laser, ultrasonic, and other processes suitable for processing and use under conditions of less than 650 ℃. PCD die Co base has two die blanks: self-supporting and tungsten carbide-supported die blanks.

The Advantages of PCD Cobalt-Based Drawing Dies

  1. Cobalt-based PCD wire drawing die blank contains metal bonds and has good processing properties.
  2. Can use electric sparks, lasers, ultrasonic, and other processes for processing
  3. The presence of metal cobalt makes it easy for diamonds to graphite at high temperatures.
  4. PCD die blank is suitable for processing and use at less than 650 degrees Celsius conditions
