CPG EDM Drilling Consumables
Copper has better EDM wear resistance than brass, but is more difficult to machine than either brass or graphite. Copper is also more expensive than graphite. Copper is useful in the EDM machining of tungsten carbide, or in applications requiring a fine finish.
Copper Tungsten Tubing
Copper tungsten materials are composites of tungsten and copper. They are produced using powder metallurgy processes. Copper tungsten is very expensive compared to other electrode materials, but useful in making deep slots under poor flushing conditions, and in EDM machining of tungsten carbide. Copper tungsten materials are also used in resistance welding electrodes and some circuit breaker applications.
Brass is an alloy of copper and zinc. Brass materials are used to form EDM wire and small tubular electrodes. Brass does not wear as well as copper or tungsten, but is much easier to machine and can be die-cast or extruded for specialized applications. EDM wire does not need to provide EDM wear or arc erosion resistance since new wire is fed continuously during the EDM wiring cutting process.
