Description£º
Tungsten-Copper alloy is the composite of Tungsten and Copper, which own the excellent performances of Tungsten and Copper, such as heat-resistant, ablate-resistant, high-intensity, excellent thermal and electrical conductivity. It is easyto be machined. It is used widely in such industries as engine, electrical power, electron, metallurgy, ***ceflight and aviation. Using CIP formation, sintered tungsten skeleton and infiltrating copper (silver) technology, large size and special shape products of tungsten-copper (silver) composites with 6-90 percent of copper are produced, such as electric contacts, electrode, refractory parts, heat sinks and parts of rocket, We can also produce sheet material, tubing, plate andother small products by mould pressing, extrusion pressing and MIM.

Applications of Copper Tungsten Composites
Resistance Welding
The high physical and mechanical properties, as well as the thermal and electrical conductivity, of refractory metal composites make these materials very suitable for die inserts and electrode facings, flash and butt welding dies, and hot upsetting. They can also solve heat balance problems.
Heat Sinks
Hogen Industries developed CuW75 to be used extensively in thermal mounting plates, chip carriers, flanges, and frames for high-power electronic devices. As a copper tungsten material, it¡¯s a composite, so both the thermal advantages of copper and the very low expansion characteristics of tungsten can be utilized.
The combination of these two materials results in thermal expansion characteristics similar to those of silicone carbide,aluminum oxide, and beryllium oxide, us |
