Alloy 290/Manganin 43 manganese copper-manganese-nickel alloy wire for precision wire wound resistors
The alloy is used for the manufacture of resistance standards, precision wire wound resistors, potentiometers, shunts and other electrical
and electronic components. This Copper-Manganese-Nickel alloy has a very low thermal electromotive force (emf) vs. Copper, which
makes it ideal for use in electrical circuits, especially DC, where a spurious thermal emf could cause malfunctioning of electronic
equipment. The components in which this alloy is used normally operate at room temperature; therefore its low temperature coefficient
of resistance is controlled over a range of 15 to 35ºC.
Manganin wire is a copper-manganese-nickel alloy (CuMnNi alloy) for use at room temperature. The alloy is characterized by very low thermal electromotive force (emf) compared to copper.
Manganin wire is typically used for the manufacturing of resistance standards, precision wire wound resistors, potentiometers, shunts and other electrical and electronic components.
