Products brief introduction
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.
Tungsten (W) Copper (Cu) Alloys are easily machinable, known for high arc resistance, high performance under vacuum, good electrical and thermal conductivity, and low thermal expansion. They have a wide variety of applications, including heat sinks and spreaders for passive cooling of electronics, electronic packaging materials, and IGBT modules for hybrid and electric vehicles.
