Product Description
Tungsten copper
Medium and High voltage circuit breakers with arcing contacts are made of tungsten copper, which is utilized for arcing contacts. The arcing contacts located at the center of the switching chamber are subjected to tremendous thermal and mechanical stresses. During arcing, temperatures can reach as high as 20,000 K, according to some estimates. Metals such as tungsten copper, which NIKO STEEL AND ENGINEERING LLP provide, have distinct material qualities. One of the most significant advantages of tungsten is its high level of temperature resistance, while the copper presence boosts both the thermal and electrical conductivity.

We can optimize the arc erosion qualities of the product by selecting the optimum amounts of tungsten and copper. This study found that tungsten concentration of 80 percent by weight results in moderate arc erosion rates. We may change the tungsten content by weight between 60 and 90 percent by weight, depending on the current and voltage intensity, as well as on economic considerations, to fulfill your exact specifications.
