Application: Special precision mold electrical discharge machining.
Tungsten-copper alloy material is a high-temperature flame-retardant composite material, which is made of metal tungsten and copper powder penetrated at high temperature. It has the characteristics of high melting point, high specific heat, wear resistance, etc., and has good thermal conductivity and electrical conductivity.
1. High hardness, low consumption, and can shorten the electrode length.
2. High conductivity and fast processing speed.
3. The high hardness and high conductivity allow tungsten carbon steel materials that cannot be discharged by ordinary copper to be processed smoothly.
4. High tensile strength, suitable for complex shape processing.
5. Long-term discharge can maintain the integrity of the copper shape, so the mold accuracy is high.
6. The structure is uniform and the contact surface loss is small.
7. High-speed operation and good stability.
