Tungsten Copper Bar 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.
Tungsten Copper Bar 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.
