What Is Tungsten Copper Heat Sink

Tungsten copper heat sink 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.

Advantages

High thermal conductivity, Excellent hermetic, Excellent size control, surface finish and flatness, Semi-finished or finished (Ni/Au plated) products available properties of WCu and MoCu heat materials.

Tungsten Copper Heat Sink Picture

Tungsten copper heat sink 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.

Tungsten copper high performance composites are fabricated from carefully controlled porous tungsten that is vacuum infiltrated with molten copper. This results in a WCu composite that has high conductivity and a matched low thermal expansion for heat sinks. The products are widely application in the fields such as radio frequency, microwave, high power diode packaging and optical communication system.
