Tungsten-Copper alloy(W-Cu alloy) is the composition of tungsten and copper, which combine the excellent properties of tungsten and copper, such as high density, high thermal conductivity, strength and rigidity, low electric resistivity and thermal expansion coefficient, electric-erosion resistance, etc

For their excellent properties, tungsten-copper alloys are widely used as switch contacts of high voltage electrical equipment, throat gasket of rocket and electrodes in electric spark, etc..
