ferrosilicon aluminum magnetic powder core is a kind of metal soft magnetic powder core produced by powder made of al5.4%, si9.6% and fe81% alloys. the iron-silicon aluminum magnetic powder core is generally coated in black. ferrosilicon aluminum magnetic powder core can be used in the shape of ring type, e-type, u-type, r rod type, i type, q tank type and other iron silicon aluminum magnetic powder core because of the excellent characteristics of various metal soft magnetic powder core and low price, has become the current three kinds of alloy series of soft magnetic powder core use of the largest, the most widely magnetic conductivity from the μe10~μe147, usually can replace mpp and other places, can be switched to ferrosilicon aluminum magnetic powder core, due to the increase in demand, its process and performance is constantly optimized.because of its distributed air gap, ferrosilicon aluminum magnetic powder core is especially suitable for energy storage and filter inductance in switching power supply. because of its high bs value and low loss, it has higher energy storage capacity compared with the same volume and magnetic conductivity iron powder core and ferrite, so it is widely used in reverse excitation transformer, pulse transformer, power factor correction circuit (pfc). because of its stable performance at high temperatures, it can be smaller than the iron powder core, and now it is also used for transformers instead of iron powder cores. no noise is generated when passing through large ac voltages, and the 0 magnetostrictive properties can also be used for noise filter inductors.
