Chinatungst Online copper tungsten sheet is a composite of tungsten and copper. The coefficient of thermal expansion (CTE) of the composite can be designed by controlling the content of tungsten, matching that of the materials, such as Ceramics (Al2O3, BeO), Semiconductors (Si), Metals (Kovar), etc. The products are widely application in the fields such as radio frequency, microwave, high power diode packaging and optical communication system.
It owns not only the low expansion of tungsten and high heat conductivity of copper. Its expansion index and heat conductivity can also be changed through changing the content of the materials, which provides convenience to the using of the material. We can supply various specifications and the Copper tungsten sheet with different tungsten proportions.
