Copper Tungsten Heatsink

What is Copper Tungsten Heatsink?

Chinatungsten specialize in providing our customers with precision machined components in a wide range of materials. The project highlighted here is composed of copper tungsten heatsink, and designed for an aerospace application. This composite metal exhibits excellent thermal conductivity, making it an ideal choice for close-tolerance parts that are exposed to high temperatures and other extreme conditions.

Copper tungsten heatsink poses various machining challenges, however we have worked closely with defense industry engineers to develop processes that produce finish qualities that meet their performance objectives.

We are able to produce in quantities of one million copper tungsten heatsink per year, it is critical that these devices operate reliably when exposed to the extreme stresses found in military applications. We source high quality 90/10 CuW from a trusted vendor, and machine the 5 mm x 6 mm x .75 mm parts with precision CNC equipment. The required Nickel and gold plating is applied with our unique and innovative chemical processes that produce an impenetrable, RF hardened, and long lasting finish. These advanced processes have earned us a worldwide reputation as a leader in the field of CuW plating.

At each step, ultra precise inspection and metrology equipment is used to verify that we maintain the required dimensional tolerances ± 0.02 mm, and uniform plating thicknesses of 1 micron. Reliable communication equipment is vital in military applications and our expertise in material sciences and plating technologies enables us to meet the high standards our partners in the aerospace industry expect.

With the thermal advantages of copper with the very low expansion characteristics of tungsten, copper tungsten heatsink has properties similar to those of silicone carbide, aluminum oxide, and beryllium oxide. The thermal conductivity and low expansion also make copper tungsten heatsink an excellent choice even for extremely dense circuits.
