Tungsten Copper Contact Spare

Tungsten copper contact spare is an alloy composite of tungsten and copper which has the combination s of the excellent properties of tungsten and copper, such as heat resistance, aberration resistance, high density, excellent thermal and electrical conductivity.

Tungsten copper contact spare is 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.

Application

Tungsten copper contact spare is the best suitable material for electrical discharge machining (EDM) applications. It has excellent wear resistance, good metal removal rate and ability to retain good detail. It is used where speed and wear resistance are most important.

Tungsten Copper Contact Spare Picture

Tungsten copper contact spare 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 copper contact spare is also used as arcing edges of selector switchblades in transformer tap changers.
