WCu Alloy Electrode Contact

Tungsten-copper (WCu) alloy electrode contacts are a pseudo-alloy composite material composed of high-melting-point tungsten and highly conductive copper. Due to their unique physicochemical properties, they play a crucial role in electrical engineering applications requiring high voltage, high current, and resistance to arc erosion. Widely used in the contacts of high-voltage circuit breakers, disconnectors, and grounding switches, their arc erosion resistance and anti-welding properties ensure reliable switching and extended lifespan. Because of their comprehensive performance advantages under extreme electrical conditions, tungsten-copper alloy electrode contacts have become an indispensable key material in high-voltage switching, welding, and electrical discharge machining.
