Nifethal 36 is an austenitic nickel-iron alloy (NiFe alloy) with very low thermal expansion factor up to 180C (356F). The alloy is characterized by good mechanical resistance, ductility and malleability combined with corrosion resistance. Nifethal 36 is magnetic over its normal range of use.
Nifethal 36 is a standard alloy for applications where a low thermal expansion is required, up to a maximum of 180C (356F), which should not be exceeded.
Typical applications for Nifethal 36 are in thermostats bars, wires for precision measuring instruments and ignition cables for the automotive industry.
