1. Brief introduction:

   Fe-Ni soft magnetic alloy: it has high permeability and low coercivity in weak magnetic field. In high-frequency and pulse technology, it is used to manufacture transformers, relays, choke core, and magnetic shield, etc. It is a necessary magnetic material for modern radio electronics industry and instrument industry.
