Fe-based amorphous alloys (Fe-based amorphous alloys)
Fe-based amorphous alloy is 80% Fe and 20% Si, B class metal elements, it has a high saturation magnetic induction (1.54T], permeability, magnetizing current and iron loss are better than silicon and other characteristics, especially low iron loss (1/3-1/5]-oriented silicon steel sheet, instead of silicon can be energy-efficient distribution transformers do 60-70% Fe-based amorphous alloy with a thickness of 0.03 mm, widely used in distribution transformers, high-power switching power supply, pulse transformers, magnetic amplifiers, intermediate frequency transformer and inverter core, suitable for use at frequencies below 10kHz.
