Tungsten copper is a composite of tungsten and copper. It combines the properties of both metals, resulting in a mixture material that is heat-resistant, wear-resistant, highly thermally and electrically conductive, and easy to machine. Tungsten copper are widely used in mechanical, electrical, electronics, metallurgy, aerospace and other industries as being electrical vacuum contact materials, EDM and ERW electrodes, electronic packaging materials, as well as precise components used in rockets, missiles and other special-purpose.
MD Tungsten & Molybdenum Company supplies tungsten copper composites from 50W-50Cu to 90W-10Cu, by using isostatic pressing, high-temperature sintering and copper infiltration process. We can produce semi-finished forms like plate, sheet, rod, bar, tube, as well as complicated custom-shaped forms by die molding, extrusion or injection molding, in large or very small sizes.

Copper tungsten (CuW, WCu) has been recognized as a highly conductive and erasion resistant composite material that is extensively used as copper tungsten electrodes in EDM machining and resistance welding applications, electrical contacts in high voltage applications, and heat sinks and other electronic packaging materials in thermal applications.
The most common tungsten/copper ratios are WCu 70/30, WCu 75/25, and WCu 80/20. Other common compositions include tungsten/copper 50/50, 60/40, and 90/10. The range of available compositions is from Cu 50 wt.% to Cu 90 wt.%. Our tungsten copper product range includes copper tungsten rod, foil, sheet, plate, tube, tungsten copper rod, and machined parts
