1.Features, High permeability High saturation induction , low core loss The density and lamination coefficient of nano-crystalline is lower than that of Permalloy, under the condition of the same size and similar performance of the Two. It is 1/4 lighter in weight, and 1/3 lower in the manufacturing cost. Good temperature stability:work for a long time at temperature of -55 ~ 130 , The linear range of nano-crystalline alloy is wider than that of permalloy .
