Amorphous core


⑴ Fe-based amorphous cores: in almost all of the amorphous alloy core has the highest saturation magnetic flux density (1.45 ~ 1.56T), also has high permeability, low coercivity, low loss, low exciting current and good temperature stability and aging stability is mainly used to replace silicon as the various forms, different power frequency distribution transformers, IF transformers, operating frequency from 50Hz to 10KHz; as a high-power switching power reactor core, frequency up to 50KHz.

⑵ Fe-Ni-based amorphous cores: medium-low saturation magnetic induction (0.75T), high permeability, low coercivity, wear and corrosion, good stability to replace commonly used in the permalloy core as GFCI the zero-sequence current transformer core.

⑶ Co-based amorphous core: in all the amorphous alloy core has the highest permeability, but also has a low saturation magnetic induction medium strength (0.65T), low coercivity, low loss, excellent wear and corrosion resistance, good temperature stability and aging stability, resistance to shock and vibration is mainly used to replace permalloy core and ferrite core production of high-frequency transformers, filter inductors, magnetic amplifiers, pulse transformers, pulse compressors and other applications at the high end (military)
