W80Cu20 Heat Sink

The tungsten copper alloy, a part of copper and tungsten, forms the aluminum of electronic packaging technology. With wrought Tungsten metal, it forms it's heat sink. The quantity of tungsten in the composite is adjustable to match the properties of other materials such as BeO, Al2O3, Kovar, Si, etc. and can also be used to control the Coefficient of Thermal Expansion (CTE).

The products are widely application in the fields such as radio frequency, microwave, high power diode packaging and optical communication system.

Besides, MoCu alloys are made by sintering molybdenum and copper together. This results in a tungsten copper heat sink of lower density, low CTE and excellent thermal conductivity. Mo-Cu is much lighter than W-Cu so that it is suitable for aeronautic and astronautic applications.

The W80Cu20 heat sink is composed of tungsten in the ration of 80% with 20% copper. Tungten is suited for this application because it has a very high melting point and is quite hard, copper on the other hand will ensure that the required heat is easily conducted and the two together will complement each other. The W80Cu20 heat sink has excellent thermal conductivity and mechanical properties, its thermal expansion coefficient is compatible with some semiconductor chips and other electronic components, greatly minimizing the risk of poor contact due to differences in thermal expansion, is very temperature shock resistant, and can endure multiple hot and cold cycles without damage.

The W80Cu20 heat sink has found great used within electronics or electrical devices that need efficient heat management. In server farms, it helps in timely heat removal from processors and graphic cards within computer server units to maintain stable function without performance dip or shutdown due to overheating. With laser equipment, it assists in timely heat removal from key components such as laser diodes to enable stable and powerful output. In advanced communication base stations, this heat sink assists in cooling important parts  such as radio frequency modules, maintains high-quality transmission of communication signals, and extends the overall service life of the equipment.
