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 ...
2013428 · Material removal rate (MRR) Ra (roughness average) surface finish. Copper tungsten can improve EWR, because of both its innate structural integrity and its resistance to “DC arcing,” a common EDM-related frustration. The MRR, or cutting speed, is largely dependent on the interaction between material properties and machining

201836 · Copper tungsten (tungsten-copper, Cu-W, or W-Cu) alloy is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite than a true alloy.
