Tungsten copper alloy is high tungsten powder and high conductivity copper powder together. Though Static pressure forming, High temperature sintering，Melting process to become Composite metal materials.Good conductivity, Low thermal expansion, High temperature non softening. high strength, high density, high density, High hardness.

Tungsten copper electrode has Greater strength, Faster heat dissipation speed, Better conductivity and thermal conductivity, More excellent high-temperature resistance and arc erosion resistance. It suitable for use in EDM

In EDM, the useful for electrode material is Conveying processing pulses and small loss to erosion of workpieces. So it must be meet the following conditions: 1. High conductivity 2.can effectively remove metal 3. Small self loss 4. Easy to process  5.material should be meet high melting point 6. Low coefficient of thermal expansion 7. Good mechanical performance.

The requirements for tungsten copper electrode for EDM as follow

1. the tungsten copper material must be has a good conductivity and thermal conductance. And also need have resistance to electric spark corrosion

2. For keep the stability during EDM and improve the Utilization rate.it need tungsten copper material has high uniformity and density. 

3. EMD electrode will according to the mold and products request to supply the similar copper tungsten electrode.
