1. Low coercivity and high initial permeability -- it can reduce the action current of leakage switch

2. The saturation magnetic induction intensity is higher than permalloy -- which is conducive to selecting a higher working magnetic induction point

3. High permeability - greatly improve the accuracy of the transformer and reduce the specific difference

4. Light weight and low cost -- the price is obviously better than permalloy

5. It has good overload resistance and good temperature stability - it can work at 55 ~ 130 ℃ for a long time
