Product Description

Source Factory  CuNi19 Foil Annealed Bright

CuNi19 is a copper-nickel alloy (Cu81Ni19 alloy) with low resistivity and can be used at temperatures up to 300°C.
CuNi19 is a low-resistance heating alloy. It is one of the key materials for low-voltage electrical products. It is widely used in low-voltage electrical products such as low-voltage circuit breakers, electric blankets, thermal overload relays, etc. It is commonly used in low-temperature applications such as heating cables.
