  • Taking a Second Look at Copper-Graphite Electrodes

     · Electrode Wear One of the disadvantages of using a copper-graphite material is increased electrode wear due to copper breaking down at a much lower temperature than graphite. Copper melts around 1 083°C while graphite will sublime around 3 350°C. The graphite porosity is filled with copper which speeds the rate of material erosion.
