Zhuzhou Guangsheng Cemented Carbide Co., Ltd. developed a new product - tungsten copper electrode.

Tungsten-copper alloy electrode is a composite metal material which is a combination of high-purity tungsten powder and high-conductivity copper powder with high purity and high plasticity, and is refined by static pressing, high temperature sintering, and melting. Good electrical conductivity, small thermal expansion, no softening at high temperature, high strength, high density, high hardness.

The classification includes resistance welding electrodes, EDM electrodes, and high voltage discharge tube electrodes.

Tungsten copper alloys are necessary in applications where high heat resistance, high electrical and/or thermal conductivity, and low thermal expansion are combined. Some applications are in resistance welding, as electrical contacts, and as heat sinks. Due to the arc erosion resistance of the alloy contact material. Tungsten copper alloys are also used in electrical discharge machining and electrochemical machining electrodes.

CuW75 is widely used in thermal mounting boards, chip carriers, flanges, and high power electronic device frames. As a composite material of tungsten and copper, it has both the thermal properties of copper and the excellent characteristics of low expansion.

Tungsten-Cu alloys are widely used in dense packaging circuits due to their thermal conductivity and expansion characteristics. 70-90% of tungsten alloys are used in the production of some special shaped products. The permeability coefficient of 1.3 enhances the copper homogeneous steel target because of the increase in both density and rupture time. Tungsten powder-type liner, especially suitable for oil drilling. Other ductile metals can be used in place of copper as well as binders. Graphite can be added with lubricant powder.
