Abstract
This invention relates to a Fe-Ni based high permeability amorphous alloy consisting of, in atom percent Ni 30-45%, Cr 0.5-1.2%, Si 5-14%, B 5-15%, P 1.0-3.0%, the balance Fe and inevitable impurities. The alloy is made by the rapid quenching melt method. It can be heat-treated in air and the excellent magnetic properties can be obtained as follows: B10 7900 Gs, Br 7500 Gs, HC 0.008 Oe, um 68×104. The present alloy is applied to make various magnetic devices which are used in electric apparatus and equipments.
