Tungsten Copper Switch Contact

Tungsten Copper Switch Contact

Description
Tungsten copper switch contact can be used as electrical contact material, owing to the good performance of electrical conductivity. The high electrical and thermal conductivity of copper are combined with the arc-resistant and non-welding properties of tungsten or their carbides to form an extensive series of compositions. Each tungsten copper product is designed to give the best performance for your particular application.

These materials are used for such heavy duty contact applications as:
Switch contacts, circuit breakers, air & oil immersed (SF6 circuit breakers)
Arcing tips or arc runners
Make & break contacts
Heavy duty conductors, relays & switches.

Package and Transportation
We pack tungsten copper switch contact in plywood case and send them by ocean or air.
