Copper Manganese Nickel

Non Ferrous are one of the leading suppliers of metals in the UK. CuMnNi are precision resistance alloys, with moderate resistivity, low temperature coefficient of resistance & low thermal electromotive force in comparison to Copper.

Copper Manganese Nickel has high stability of electrical resistance, good working properties & very good weldability.

CuMnNi alloys are specially dedicated to Precision resistors & Electrical shunts.

These control and measure the current flowing through devices such as Electricity meters or DC ammeters.
