Tungsten copper wire and tungsten copper electrodes were used in EDM (Electrical Discharge Machining) and resistance welding in the early 1960s. Due to its high density, high strength, and the remarkable electric and thermal conductivity, as well as resistance to arc ablation, tungsten copper was used. To date, and with the developments of related technologies alongside further research studies, tungsten copper has started being utilised in the processing of plasma electrode materials, precision machining, spraying, LEDs, and other electrodes. However, the special PM structure of tungsten copper has considerably limited wire use. Addressing uniformity, mechanical characteristics, and production costs requires the adoption of different and innovative technologies and processes.

In EDM electrodes, tungsten copper wires must fulfil several criteria:

1. Due to its exceptional resistance to spark erosion, it is first mentioned for its excellent thermal and electrical conductance.  

2. Better stability of electrical processing and improvement in the availability of electrode material are contributed to by a uniform structure and higher density.

3. The overall effectiveness, quality, and machining efficiency are all positively affected by low machining consumption.

4. Designing, finishing, and machining tungsten copper electrode bars of various profiles are all dictated by the ease with which they can be made. Complex shapes are not an exception.
