SELECTION OF ELECTRICAL STEELS FOR Magnetic Cores

Silicon is the primary alloying element in electrical steels. It is added because it increases the volume resistivity of the steel and thereby reduces the eddy current component of core loss. Silicon is more effec-tive in this respect than any other element which may be conveniently added. Silicon …

Electrical steel - Wikipedia

Commercial alloys usually have silicon content up to 3.2% (higher concentrations usually provoke brittleness during cold rolling). Manganese and aluminum can be added up to 0.5%. Silicon increases the electrical resistivity of iron by a factor of about 5; this change decreases the induced eddy currents and narrows the hysteresis loop of the material, thus lowering the core loss .
