Tungsten copper electrodesare used where the combination of high heat resistance, high electrical and/or 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. Tungsten copper alloys are also used in electrodes for electrical discharge machining and electrochemical machining.It has some notable features ：better heat resistant;better ablate-resistant;high intensity;high density;excellent thermal and electrical conductivity;easy to be machined etc.

Tungsten copper alloy with 70~90% of tungsten is used in liners of some specialty shaped charges. The penetration is enhanced by factor 1.3 against copper for homogeneous steel target,
as both the density and the breakup time are increased. Tungsten powder based shaped charge liners are especially suitable for oil well completion. Other ductile metals can be used as binder in place of copper as well. Graphite can be added as lubricant to the powder.
