Material Notes:
WCu composites are made by vacuum infiltration of uniform controlled porous blocks of tungsten with molten copper. This results in a material with an interconnected Cu matrix that has high thermal conductivity in all axes, low CTE, and good electrical conductivity. These properties lead to applications in demanding uses such as high voltage arc contacts, vacuum contacts, electrodes for resistance welding and spark erosion, heat sinks and spreaders, microwave carriers, hermetic package bases and housings, ceramic substrate carriers, GaAs and silicon device and laser diode mounts.Data provided by the supplier, MarkeTech International.
