CuNi30Mn 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.
Material: CuNi5 CuNi10(C70600) CuNi20 (C71000) CuNi25(C71300), CuNi30(C71500) in from of sheet/plate/strip
