Copper–tungsten - Material DB - RoHS - Reach

Copper tungsten arc contacts resist arc erosion. The Spark Erosion (EDM) process calls for copper tungsten. Usually, this process is used with graphite, but as tungsten has a high melting point (3420 0 C) this allows the CuW electrodes to have a longer service life than the graphite electrodes. This is crucial when the electrodes have been ...

Applications Considerations

2021224 · Tungsten Tungsten contacts are for use in high voltage applications, usually where highly repetitive switching is required. Tungsten has a melting temperature of 3,380oC which gives it excellent arc-erosion resistance. Tungsten may develop troublesome oxide films, especially when used as the anode contact in some DC applications.
