FeSiB Alloy Strip

Application area:

Frequency transformer iron core(50-60Hz)

IF power transformer iron core (400Hz-15kHz)

Switch power transformer iron core ( below 10kHz)

Filter reactor, filtering and energy storage inductor,

Power factor correction inductor core( below 50kHz)

Saturable reactor、Pulse compressor iron core

  • High Saturation magnetic induction - reduce transformer volume

  • High magnetic permeability low coercive force- improve transformer efficiency

  • Low loss(Equivalent 1/3 1/5 of silicon steel sheet)- reduce transformer temperature rise

  • Low magnetizing current - reduce primary coil copper loss of  transformer

  • Good temperature stability -  under 130℃ for long-term work
