Tungsten copper contact


Tungsten copper contact is also called tungsten copper point. Tungsten copper contact is widely used in high voltage applications where there requires highly repetitive switch.

Tungsten has a high melting point, which gives tungsten excellent arc-corrosion resistance. Tungsten copper contact is a combination of copper and tungsten. Tungsten copper contact is a cost efficient relay contact and can resist arcing and corrosion. While tungsten copper contact should be regularly cleaned and burnished.Tungsten copper contact is suitable to be used in the circuit.

Tungsten copper contact can be made from tungsten copper rod or tungsten copper disk.

As for quality, we double-check materials before beginning production. We also conduct stringent inspections to ensure durability and specifications to meet your requirements.Buyers from US and India come to us for tungsten and molybdenum products and we have cooperated for over 10 years.

Tungsten Copper Alloy

Tungsten copper (copper tungsten, CuW, or WCu) alloy is a pseudo-alloyof tungsten and copper. 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. The microstructure is therefore rather a metal matrix composite than a true alloy.Copper Tungsten alloy 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.

Tungsten Copper Alloy Main applications: For the spark erosion of dies of cemented carbide and for making high speed steel and switches and contacts in high and low voltage electrical devices.

Tungsten Copper materials

Electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing. Only Tungsten Copper materials will stand these high temperature & aberration.


Tungsten Copper material has good resistance to arc erosion, mechanical wear, contact welding and good conductivity. They are usually selected for oil, gas, air or vacuum, devices. The contact surfaces will oxidize when switched in air. These press-sinter-infiltrate materials should only be considered for arcing surfaces in air when used as arcing tips, arc plates and arc runners. When switching with moderate contact arcing, the Tungsten Copper with a high copper content may give the lowest erosion. As arcing severity increases, the Tungsten Copper with the higher refractory content withstand arc erosion better. Tungsten Coppers are also used as arcing edges of selector switchblades in transformer tap changers.
