Copper-nickel alloy





Copper base low resistance heating alloy material:
Copper-based low resistance heating alloy is widely used in low-voltage circuit breakers, thermal overload relays and other low-voltage electrical products. Low-voltage electrical products is one of the key materials. My company produces copper-based low-resistance heat-resistant alloy material with good resistance consistency, stability and excellent features. Companies can supply a variety of round wire, flat and strip.
