Tungsten copper alloy (Copper Tungsten Alloy, CuW, or WCu) 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 alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, and easy to machine. Parts are made from the WCu alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.
Copper Tungsten WCu Alloy can also be used as a contact material in a vacuum. When the contact is very fine grained , the electrical conductivity is much higher than a normal piece of copper tungsten Copper tungsten is a good choice for a vacuum contact due to its low cost, resistance to arc erosion, good conductivity, and resistance to mechanical wear and contact welding. CuW is usually a contact for vacuum, oil, and gas systems. It is not a good contact for air since the surface will oxidize when exposed. CuW is less likely to erode in air when the concentration of copper is higher in the material. The uses of CuW in the air are as an arc tip, arc plate, and an arc runner.
Copper tungsten materials are often used for arcing contacts in medium to high voltage sulfur hexafluoride circuit breakers in environments that can reach temperatures above 20,000K. The copper tungsten material's resistance to arc erosion can be increased by modifying the grain size and chemical composition.

Copper Tungsten WCu Alloy Picture:
Copper Tungsten WCu Alloy Usually, this process is used with graphite, but as tungsten has a high melting point (3420 °C) this allows the CuW electrodes to have a longer service life than the graphite electrodes. This is crucial when the electrodes have been processed with complex machining. Since the electrodes are susceptible to wear the electrodes provide more geometrical accuracy than the other electrodes. These properties also let the rods and tubes manufactured for spark erosion be made smaller in diameter and have a longer length since the material is less likely to chip and warp.
