Copper tungsten is an alloy composed of copper and tungsten, offering a unique combination of high electrical conductivity from copper and excellent heat resistance and wear resistance from tungsten. This makes it an ideal material for applications in environments that require both high thermal and electrical performance.

In Electrical Discharge Machining (EDM), copper tungsten is widely used for making electrodes due to its ability to withstand the high temperatures generated during the machining process. The material’s excellent thermal conductivity helps dissipate heat quickly, reducing wear and extending the lifespan of the electrode. Copper tungsten electrodes are often used in precision machining of hard materials, such as tool steels and carbide, where durability and performance under high-stress conditions are essential.
