Where Is Manganin Used?

Manganin foil and wire is used in the manufacture of resistors, particularly ammeter shunts, because of its virtually zero temperature coefficient of resistance value and long term stability.

Why is manganin used for making?

Alloys like manganin and constantan are used for making standard resistance coils as they have high resistivity, low-temperature coefficient of resistance. Therefore, these alloys are used for making wire-bound standard resistors. Their resistance value would change very little with temperature.

Is manganin expensive?

It is relatively expensive because wirewound resistors cannot be made by economical deposition processes but must be physically wound and physically connected to the terminals. Furthermore they are not good for high frequency use nor are they small.
