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