Application of CuNi1
CuNi1 low resistance heating alloy is widely used in low-voltage
circuit breaker, thermal overload relay, and other low-voltage
electrical product. It is one of the key materials of the
low-voltage electrical products. The materials produced by our
company have the characteristics of good resistance consistency and
superior stability. We can supply all kinds of round wire, flat and
sheet materials.
