Tungsten Copper Alloy Bar
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 Copper Tungsten Alloy combines the properties of both copper and tungsten, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, and easy to machine.
Description
Product Description
Tungsten Copper Alloy bar 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. WCu alloy is easy to be machined. WCu alloy is used widely in such industries as engine, electrical power, electron, metallurgy, spaceflight and aviation.
Tungsten Copper Alloy products are made from the WCu alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper. Besides Tungsten Copper Alloy bar, Sheets or Plates are available as well.
