Explore the development of high density soft magne
 
Powder metallurgy technology can produce complex shapes and with good magnetic properties of soft magnetic materials, powder metallurgy technology has been successfully applied to large-scale commercial production of soft magnetic materials. It has been used as soft magnetic powder metallurgy commodity production materials: iron, phosphorus, iron, nickel, iron, cobalt, iron and ferrosilicon. Addition of silicon and would not improve the iron-based soft magnetic properties of materials, silicon can be added to increase the resistance of iron-based materials to reduce eddy current loss materials to improve high frequency performance soft magnetic materials. Ferritic stainless steel magnetic material has been produced and used, ferritic stainless steel magnetic material with good corrosion resistance, but the soft magnetic properties will decline.
