Tungsten copper
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.
