Cuni30 Copper Nickel Alloy wire in Electric Power Industry

Short Description:

Copper Nickel (CuNi) alloys are medium to low resistance materials typically used in applications with maximum operating temperatures up to 400°C (750°F). With low temperature coefficients of electrical resistance, resistance, and thus performance, is consistent regardless of temperature. Copper Nickel alloys mechanically boast good ductility, are easily soldered and welded, as well as have outstanding corrosion resistance. These alloys are typically used in high current applications requiring a high level of precision. Material: CuNi5 CuNi10(C70600) CuNi20 (C71000) CuNi25(C71300), CuNi30(C71500) in from of sheet/plate/strip Product Description: CuNi30 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.
