Cu-ni low-resistance heating alloy is widely used in low-voltage electrical products such as low-voltage circuit breaker and thermal overload relay, and is the key material in low-voltage electrical products
One of the materials. It has the characteristics of good resistance consistency and excellent stability.
Main properties of copper-nickel low resistance heating alloy:
