Copper Tungsten Alloy

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. Most sizes and shapes can be supplied with short lead times. We can also manufacture parts from these materials to your specifications.
