I . Characteristic:
Low temperature coefficient of resistance value and long term stability, also has low strain sensitivity but high hydrostatic pressure sensitivity.
II . Applications:
Manganin wire is often used for cryostat wiring or heater requirements in nonmagnetic applications and also used as an electrical conductor in cryogenic systems, minimizing heat transfer between points which need electrical connections.
