Ferrosilicon FeSi3.5 Powder (Gas-atomized) Description

Ferrosilicon FeSi3.5 Powder is processed into a metal soft magnetic core through insulation and coating, followed by a powder metallurgy process. It possesses unique functions such as magnetoelectric conversion and energy storage filtering. The insulating coating layer on the surface of the powder effectively enhances its electrical resistivity, resulting in lower losses under medium and high-frequency conditions. Additionally, the thin insulating layer has minimal impact on the material's saturation magnetic induction.
