Introduction
CuNi6 resistance alloy is a kind of copper nickel binary alloy with low temperature coefficient of resistance and a maximum operating temperature of 250°C. This alloy is mainly used to manufacture low voltage circuit breaker, low temperature electric blanket, thermal cutout and other low voltage electrical devices. It is also used to produce heating cable for home electric blanket.
