Product Description
CuNi23 alloy wire: 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.ng cable.
