Copper Tungsten Heatsink

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.

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.

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.

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.

Tungsten Copper Liner

Tungsten copper alloy is made of copper tungsten and face-centered cubic structure of body-centered cubic structure consisting of neither miscible, nor a two-phase mixed structure of intermetallic compounds, often referred to as a pseudo-alloy. Therefore, it has both high strength and hardness, low coefficient of expansion characteristics of tungsten; while there are high plasticity of copper, good electrical and thermal conductivity, this unique combination of properties make tungsten copper alloy is widely used especially due sigh tungsten copper alloy tungsten composite having a high density and high toughness of copper and attention.

Tungsten copper liner is very sensitive to bomb high charge, the rapid decline in large frying depth to compete with armor, the best fried high as 3 times the diameter size. This is also the presence of tungsten copper liner in common: in a small frying condition of high depth of their armor comparable copper liners increased by about 30%, but to compete in the big frying performance is deteriorating rapidly, the jet can not get ductility. Furthermore, since the metal powder alloy and illiquid, with filling, pressing process many random factors, so that the amount of Liner quality (ie density) distribution is difficult to control, so the performance is unstable, wearing dark volatile A pair of which is to be desired.

Tungsten copper shaped combination of high density and ductility of tungsten copper, compared to copper liners have higher power and armor shaped effect. The disadvantage is that tungsten and copper can not dissolve each other, and because of the density difference between the two large, easy to form when gravity segregation caused by compression molding liners inhomogeneous density distribution.

Tungsten copper alloy as an ideal material for liners, but there is more in the preparation process issue, tungsten copper alloy bonding strength is poor, molding material difficulties; its wear deep fried sensitive to high variability, it should only lower Fried use under high conditions.

electrode. One end of the material is tungsten copper alloy, the other end is a relatively high tensile strength steel. Tungsten copper with iron composite is developed in response to customer requirements, a new process technology, using a complex method of manufacturing the pressure. Combined with the end face of tungsten, copper and iron close no holes, the overall low contact resistance, and high tensile strength. Tungsten copper composite electrode material is copper, steel two materials by explosive welding composite, combined with high strength, good electrical conductivity, direct sawing, milling and grinding. In the discharge machining precision parts IC, which is a good overall performance copper electrode can not be replaced, to improve the processing accuracy of parts and reduce overall costs is the most important feature of this material. This material has been widely used in foreign countries, our company can be customized with different ways of complex products according to customer requirements.
