www.fotmacarbide.com provide Tungsten Copper Alloy Round Bar W Cu Alloy Bars W80 W75 W70 For Airplane Industry Tungsten copper (Cu-W) Alloy is the composite of tungsten and copper which own he excellent performance of tungsten and copper. It is used widely in such industries as engine, electric power, electron, metallurgy, spaceflight and aviation. Tungsten copper alloy combines the properties of both tungsten and copper metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to be machined. Main Sizes of Tungsten Copper Alloy Round Bars: Diameter: 1 - 100 mm Length: 50 - 500mm Diameter Tolerances: +/-0.05mm - 0.1mm Length Tolerances: +/- 0.1mm, +/-0.5mm Advantages of WCu Alloy Round Bars: High arc resistance High thermostability High strength Lighter weight than pure tungsten Good electrical conductivity
