Home >>Tungsten Copper Alloy >>Tungsten Copper Bar Tungsten copper alloy bar, is also called tungsten copper bar, copper tungsten bar is the composite of tungsten and copper that owns excellent properties of both tungsten and copper, such as heat-resistant, ablate-resistant, high-intensity, excellent thermal and electrical conductivity. Tungsten copper bar is easy to be machined. Copper tungsten bar is widely used in various industries as engine, electrical power, electron, metallurgy, spaceflight and aviation.

Using CIP formation, sintered tungsten copper bar skeleton and infiltrating copper (silver) technology, large size and special shape products of tungsten copper bar (silver) composites with 6-90 percent of copper are produced, such as electric contacts, electrodes, copper tungsten alloy refractory parts, heat sinks and parts of rockets, We can also produce copper tungsten bar, copper tungsten alloy sheet material, copper tungsten alloy tubing,copper tungsten alloy plate and other small copper tungsten alloy products by mould pressing, copper tungsten alloy extrusion pressing and MIM.
