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 inelectric resistance welding, aselectrical contacts, and asheat sinks. As contact material the alloy is resistant to erosion by electric arc. WCu alloys are also used in electrodes forelectrical discharge machiningandelectrochemical machining.

Coppertungsten(tungstencopper,CuW, orWCu)alloyis apseudo-alloyof copper andtungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. Themicrostructureis therefore rather ametal matrix compositeinstead of a true alloy.

Copper tungsten material list :

Production Process- Powder Metallurgy

The material combines the properties of both metals, resulting in a material that is heat-resistant,ablation-resistant, highlythermallyandelectrically conductive, and easy tomachine.

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

Commonly used copper tungsten alloy contains 1050 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 16.75 g/cm3 and 11.85 g/cm3 for CuW50 alloy. CuW90 has higher hardness and resistivity of 260 HB kgf/mm2 and 6.5 .cm than CuW50.
