What's Tungsten Copper Alloy? Tungsten copper alloy (Copper Tungsten Alloy, CuW, or WCu) is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, and easy to machine. Parts are made from the WCu alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.
Located in the well-known Tungsten city Zhuzhou, the world-renowned research and production base of tungsten molybdenum in China, we can custom machine any alloys to finished parts according to your specifications.

Applications
Copper tungsten alloy is used in a product or part requires high heat resistance, low thermal expansion and high electrical or thermal conductivity. Tungsten copper is used to fabricate engines and electrical devices. It is also used in the fields of aviation and spaceflight. Electrodes, refractory parts, heat sinks, rocket parts and electrical contacts are all made by copper tungsten alloy. The alloy is also made into sheet metal, tubing and plate metal. Copper tungsten alloy is used to make contacts for both high and medium voltage electrical devices, and for high speed steel devices and switches.
