Product Description

COMMON NAMES: Alloy 120, NF20 / Nifethal 70, MWS-120, BALCO ALLOY
NiFe alloys
Low-resistivity nickel-iron alloys with high temperature coefficient of resistance for use up to 600ºC.
Nifethal 70 is a nickel-iron alloy (NiFe alloy) for use at temperatures up to 600°. The alloy has very low resistivity and high temperature coefficient of resistance. Some applications for Nifethal 70 are in voltage regulators, timing devices, temperature sensitive resistors, temperature compensating devices and low temperature heating applications.
Nifethal 52 is a nickel-iron alloy (NiFe alloy) for use at temperatures up to 600°C. The alloy has low resistivity and high temperature coefficient of resistance. Nifethal 52 is used in voltage regulators, timing devices, temperature sensitive resistors, temperature compensating devices, and low temperature heating applications.
Nifethal 42 is a nickel-iron alloy (NiFe alloy) for use at temperatures up to 600°C. The alloys has a moderate constant thermal expansion factor up to 300°C. Nifethal 42 is used in high-temperature thermostats, for example, gas and electric stoves.

Nifethal^® 70 is a nickel-iron alloy (NiFe alloy) for use at temperatures up to 600°C (1110°F). The alloy is characterized by very low resistivity and high temperature coefficient of resistance.

Typical applications for Nifethal^® 70 are in voltage regulators, timing devices, temperature sensitive resistors, temperature compensating devices and low temperature heating applications.
