NiFe Alloys with 72-80% Ni
The alloys in this group are very soft magnetic materials. They are available in various tape thicknesses as well as in a solid material form. Their characteristic is high output and maximum permeabilities as well as low coercitivity field strengths with saturation polarizations (around 0.7 - 0.8 T).In addition, the shape of the hysteresis loop can be manipulated in very broad limits. For example, it is possible to create circular tape cores with rectangular loops (Z), round loops (R) and flat loops (F).
