It is mostly used in photovoltaic power generation, wind power generation inverter, UPS power supply and automobile charging pile.

Second, the aluminum chips are placed in the groove of the ramming machine, and screened after the aluminum becomes very thin and fine. Only by this method can the aluminum powder have metallic color and shielding function, and also have a positive particle state. The ductile aluminum gradually becomes flakes and breaks under impact. The pounding pestle is driven by the machine to continuously punch the aluminum chips in the groove. The aluminum powder particles for the pigment are scaly. Is one of the main varieties of unshaped refractory materials.

Summarize the characteristics of ferrosilicon aluminum: appropriate cost, better than molybdenum permalloy/high magnetic flux and composite alloy; lower loss, better than iron powder core; high saturation, better than gap ferrite; close to zero magnetostriction, better than iron powder core; no thermal aging phenomenon, better than iron powder core; soft saturation, better than gap ferrite and composite alloy.
