Various Size Tungsten Copper 75 25 Rings Powder Metallurgy Electrical

Various Size Tungsten Copper 75 25 Rings Powder Metallurgy


Tungsten Copper is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite instead of a true alloy.

Features


Tungsten-copper alloy has a wide range of applications, most of which are used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries. Secondly, it is also used to manufacture the contacts of high-voltage electrical switches and high-temperature components such as rocket nozzle throat liner and tail rudder, which are resistant to arc erosion, and also used as electrodes for electrical machining, high-temperature molds and other occasions requiring conductive and thermal conductivity and high-temperature use.


Applications


1. Arcing contacts and vaccum contacts in high and medium voltage breakers or vaccum interruptors

2. Electrodes in electric spark erosion cutting machines

3. Electrodes for resistance welding.
