25AWG Alloy 120 Wire NF20 / Nifethal 70 Used For Resistance Thermometers
COMMON NAMES: Alloy 120, NF20 / Nifethal 70, MWS-120, BALCO ALLOY
Alloy120 (Ni72Fe Alloy ) is a nickel-iron alloy with a thermal conductivity similar to nickel but twice the resistivity. It is used for making low cost resistance temperature sensors.
This alloy is characterized by very low resistivity and high temperature coefficient of resistance.
Its principal use is for resistance thermometers (resistance temperature detectors).
It is also mechanically strong and fairly corrosion resistant.
Ni72fe is a nickel-iron alloy for use at temperatures up to 600°C.
Typical applications for Ni72Fe:
1. Voltage regulators,
2. Timing devices,
3. Temperature sensitive resistors,
4. Temperature compensating devices
5. Low temperature heating applications.
