Soft magnetic alloys
48NiFe has expansion that matches soda-lead and soda-lime glass. Used as leads for electronic applications. It is also used in thermostats for industrial applications upto 450°C.
Introduction
These alloys are used in applications requiring the following characteristics: high permeability, high saturation magnetostriction, low hysteresis-energy loss, low eddy-current loss in alternating flux, low curie temperature, vonstant permeability with changing temperature.
