super ferrosilicon aluminum magnetic powder core is made by gas atomization granulation to make an approximate spherical iron and silicon aluminum alloy magnetic powder, which is suppressed by special forming process. the general coating of the super ferrosilicon aluminum magnetic powder core is blue.super ferrosilicon aluminum magnetic powder core has excellent ultra-low loss performance, dc bias characteristics than the traditional iron-silicon aluminum magnetic powder core increased by more than 20%, in the consideration of sexual dingxiang ratio, can be used as the second choice for high-throughput magnetic powder core applications.
