Brief description

CuW alloys are used where the combination of high heat resistance, high electrical and thermal conductivity, and low thermal expansion are needed. Some of the applications are in?electric resistance welding, as?electrical contacts, and as?heat sinks. As contact material the alloy is resistant to erosion by electric arc. WCu alloys are also used in electrodes for?electrical discharge machining?and?electrochemical machining.

Detailed description



The material 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 copper tungsten 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 copper, the remaining portion being mostly tungsten. The typical properties of the alloy depend on its 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.

 

For different application should choice the different grade copper tungsten alloy composition. The key factor is evaluating the hardness, electrical conductivity. Thread tapping is better use the Cu-W (72% by weight) tungsten composition. For some EDM electrode since it need to be machining after periods of using. The W-70% to 75% compositions is recommended.
