Characteristic and use |
It is the electric resistance alloy with copper, nickel as the essential component. It has good anti-corrosive performance, welding performance and processability. It is mainly applied in manufacturing heater resistance of low-voltage electrical appratuses, such as thermal overload relay, low-voltage circuit breaker. | ||||
