Products brief introduction
Tungsten copper materials have high heat resistance and good thermal conductivity, and at the same time, they have a thermal expansion coefficient that matches silicon wafers, gallium arsenide, and ceramic materials, so they are widely used in semiconductor materials, suitable for high-power device packaging materials, heat sink materials, heat dissipation components, ceramics, and gallium arsenide bases, etc.
Copper–tungsten (tungsten–copper, CuW, or WCu) is a mixture of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite instead of a true alloy.
The material combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.
Copper Tungsten Sheet has the advantage form both tungsten and copper:
Tungsten Copper Plate has good resistance for high temperature and arc erosion,high strength,high density,good electric and thermal conductivity,small thermal expansion,easy machining.It is widely used as electrodes of resistance welding and electric spark erosion cutting machines,arcing contacts and vacuum voltage breakers or vacuum interruptors.
