Ferrosilicium FeSi3.5 Powder (gas-atomised) Description
Ferrosilicium FeSi3.5 Powder is subjected to an insulation and coating process before being processed into a soft magnetic metal core. It is produced by a powder metallurgical method. It exhibits specific functions in magnetoelectric conversion and energy storage through filtering. The insulating coating on the powder’s surface effectively improves its electrical resistance, thereby reducing losses under medium and high-frequency conditions; additionally, the thinness of the insulating layer has a limited influence on the material’s magnetic saturation induction.
