Tungsten Copper Alloy Rod

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.

The tungsten copper alloy combines the properties of both the tungsten metals and the copper. And then resulting in a material that is heat-resistant, ablation-resistant, highly thermally, 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, then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.

Commonly used copper tungsten alloy contains 10 to 50 wt % of the copper, the remaining portion being mostly tungsten.
The typical properties of the alloy depends on their composition. The alloy with less wt. % of copper has higher density, higher hardness and higher resistivity. The typical density of CuW90 alloy, with 10% of copper, is 16.75g/cm3 and 11.85g/cm3 for CuW50 alloy. CuW90 has higher hardness and resistivity of 260 HB kgf/mm2 and 6.5 µΩ.cm than CuW50.
