Tungsten Copper Alloy - Cu + W
Consisting of pure tungsten (W) powder suspended in a matrix of copper (Cu), these alloys are readily machinable and known for good thermal and electrical conductivity, low thermal expansion, being non-magnetic, good performance under vacuum, and resistance to erosion from arcing.. Thus, they are often used as electrical contacts, particularly in high voltage appliions.
