- Details
Outline：The iron-based amorphous alloy is composed of 80%fe and 20%siand b,the alloy of the metal element is rapidly solidified.Anamorphous material formed by the art,having an extremely highquality,superior physical and electrical.
Technical Characteristics：1. High saturation magnetic induction intensity--reduce the number of winding turns,reduce thevolume of the product
2. High resistivity,low coercivity--improve product efficiency
3. Low loss(equivalent to 1/3-1/5 of silicon steel sheet)--reduce the temperature rise of the productand improve the efficiency
4. Low excitation power--reduce the no-load current of the product,reduce the copper loss of theprimary winding
5. Variable magnetic conductivity--different heat treatment processes of iron core can be used tomeet different application requirements.
6. Good temperature stability--can work at 130℃ for a long time
