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.

Tungsten Copper
Tungsten copper materials composed of two elements. Tungsten and copper do not form a solid solution, an intermetallic compound is not formed, but the respective metal components independently and uniformly exists. So start called a "fake alloy", was also classified as "composite" in. Having a tungsten skeleton (skeletal density is generally 70% to 86% of theoretical density) tungsten copper material at high temperature, the molten
copper, the heat of evaporation and absorption of the surface of the substrate W has a cooling effect, as the human body to reduce sweating Like temperature, sweating is a metal material. Tungsten has a high melting point, high strength and high hardness, copper has good electrical conductivity, thermal conductivity and toughness, tungsten, copper and copper tungsten material consolidated performance with high value.
