Mainly used in substituting for silicon steel, to make cores for all kinds of distribution transformers, medium frequency transformers, operating frequency ranges from 50Hz to 10kHz, working as large power switch reactor core material, the operating frequency can be up to 50KHZ.
Characteristics:
Ø High saturation flux density
Ø High permeability
Ø low coercive force
Ø Low core losses(1/3-1/5 of silicon steel)
Ø Low excitation current Good thermal stability and aging stability.
