Copper-tungsten sheet is a composite material of tungsten and copper. The coefficient of thermal expansion (CTE) of the composite can be designed by controlling the content of tungsten to match with ceramic (Al2O3, BeO), semiconductor (Si), metal (Kovar) and other materials. Widely used in RF, microwave, high-power diode packaging and optical communication systems and other fields.


It not only has the low expansion of tungsten and the high thermal conductivity of copper. Its expansion index and thermal conductivity can also be changed by changing the content of the material, which provides convenience for the use of the material. We can provide copper-tungsten sheets with various specifications and different tungsten ratios.

Advantages of copper tungsten alloy
High arc resistance and good electrical conductivity
High thermal conductivity
low thermal expansion
