Tungsten Copper Contacts Spares

Chinatungsten are able to provide kinds of tungsten copper contacts, and the tungsten copper contacts spares is a kind of tungsten copper contacts. It is used as electrode.

Tungsten Copper Contact Spares Picture

Tungsten copper contacts spares have 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 copper contacts spares are also used as arcing edges of selector switchblades in transformer tap changers.

Tungsten copper contacts spares materials made of WCu are also characterized by the properties of high arc erosion resistance, good electrical conductivity, excellent strength, very good machinability, good thermal conductivity and low thermal expansion.
