CuNi 23 /nickel alloy 30/Cuprothal 30
Copper Nickel 23 or CuNi23Mn is a copper nickel alloy with the addition of Manganese to produce an alloy with a relatively low resistivity but high resistance to oxidation and chemical corrosion. Maximum working temperature is 500 °C. Applications include heating cords and mats
Product Description
CuNi23Mn 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.
