l High Saturation magnetic induction - reduce transformer volume
l High magnetic permeability low coercive force- improve transformerefficiency
l Low loss(Equivalent 1/3 1/5 of silicon steel sheet)- reduce transformer temperature rise
l Low magnetizing current - reduce primary coil copper loss of transformer
l Good temperature stability - under 130℃ for long-term work
