CuNi1 Resistance Alloy
Introduction
CuNi1 resistance alloy is a type of copper nickel binary alloy with low temperature coefficient of resistance and a maximum operating temperature of 200°C. This alloy is mainly used to produce low voltage circuit breaker, low temperature electric blanket, thermal cutout and other low voltage electrical devices.
