Copper tungsten alloys are commonly used in EDM electrodes and other electrical and electrical/thermal applications. They are also used for facing and inserts for flash and butt welding dies, projection welding electrodes, seam welding bearing inserts and facing for electro-forming and electro-forging dies.
Although they are somewhat more difficult to machine, tungsten carbide copper materials provide high mechanical properties and excellent resistance to erosion. They are commonly used in oil devices to protect the contact from oxidation.
