Nifethal 52 is a nickel-iron alloy (NiFe alloy) for use at temperatures up to 600°C (1110°F). The alloy is characterized by low resistivity and high temperature coefficient of resistance.
Typical applications for Nifethal 52 are in voltage regulators, timing devices, temperature sensitive resistors, temperature compensating devices, and low temperature heating applications.
