Copper Tungsten alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.

Tungsten Copper Alloy Main applications: For the spark erosion of dies of cemented carbide and for making high speed steel and switches and contacts in high and low voltage electrical devices
Copper tungsten alloy 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. Tungsten copper alloy is easy to be machined. Tungsten copper alloy is used widely in such industries as engine, electrical power, electron, metallurgy, spaceflight and aviation. Using CIP formation, sintered tungsten skeleton and infiltrating copper (silver) technology, large size and special shape products of tungsten copper composites with 6-90 percent of copper are produced, such as electric contacts, electrode, refractory parts, heat sinks and parts of rocket, We can also produce tungsten copper alloy sheet material, tubing, plate and other small products by mould pressing, extrusion pressing and MIM.

Copper Tungsten alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.

Parts are made from the tungsten copper alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, and then infiltrating with molten copper. Sheets, rods and bars of tungsten copper alloy are available as well.
