Fe-P Soft Magnetic Properties of Iron for A.C. Applications
Silicon steels and ferrites dominate soft magnetic materials. However, Soft magnetic materials using powder metallurgical techniques are gaining wide spread use in motor, compressors and other rotating devices. High-density Fe-P soft magnetic materials have been developed using hot powder forging route. It was observed that phosphorous addition (ranging from 0.30P-0.80P) enhances the soft magnetic properties of iron for AC applications. This new soft magnetic material offers many manufacturing advantages. Because of its low eddy current loss, it has good high frequency magnetic properties comparable to other soft magnetic materials. Also, it has been observed that phosphorous addition improves the final density of the resulting product.
