Product details
Hangzhou Ualloy Material Co.,Ltd is one of the best copper nickel alloy cuni19 manufacturers and suppliers in China,Website:://.alloystrip.com, welcome to buy discount and low price nc25B from us, and also welcome to check the price and quotation with our factory. CuNi19 (Common Name:CuNi19,NC25) CuNi19 is a copper-nickel alloy (Cu81Ni19 alloy) with low resistivity for use at temperatures up to 300°C. CuNi19 is kind of low resistance heating alloy.It is one of the key materials of the low-voltage electrical products. It is widely used in low-voltage circuit breaker, electric blankets.thermal overload relay, and other low-voltage electrical product. CuNi19 is typically used for low-temperature applications such as heating cables. Normal composition% Nickel 19 Manganese 0.5 Copper Bal.
