Different variants of high Copper & low Nickel content alloys with high or low specific resistance are notable for low temperature coefficient of resistance. Possessing high resistance to oxidation and chemical corrosion, these alloys are used for wire-wound precision resistors, potentiometers, volume control devices, winding heavy-duty industrial rheostats and electric motor resistances. Different variants are used for heating cables with low conductor temperatures and as tube weldings in  “electrical welding fittings”. Copper Manganese alloy is used a standard material for precision, standard and shunt resistors.
