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.

| Product Name | Copper Nickel Alloy CuNi Wire |
| Product Description | Copper Nickel Alloy is mainly made of copper and nickel. The copper and nickel can be melted together no matter what percentage. Normally the resistivity of CuNi alloy will be higher if the Nickel content is larger than Copper content. From CuNi6 to CuNi44, the resistivity is from 0.1μΩm to 0.49μΩm. That will help the resistor manufacture choosing the most suitable alloy wire. |
| Product Features | By the way, the Copper Nickel wire is easy to be welded and easy to be fabricated, so it can be made into many forms and widely used in all areas. |
