Tungsten Copper 

 Consisting of pure tungsten (W) powder suspended in a matrix of copper (Cu), these alloys are known for good thermal and electrical conductivity, low thermal expansion, and resistance to erosion from arcing.  Thus, they are often used as electrical contacts, particularly in high voltage applications. Tungsten copper alloy are the perfect choice where high density, high thermal conductivity, or low thermal expansion are important. Electrical contacts, heat sinks, and resistance welding electrodes are all applications where tungsten copper alloy can do the job. Most sizes and shapes can be supplied with short lead times. We can manufacture parts from these materials to your specifications.
