The characteristics of such sheet steel is good magnetic and high silicon content, therefore alias is silicon steel. Mainly used in the field of the magnet, and the easy magnetization and demagnetization.
Electrical steel has lower carbon content, but the highest silicon content about 3%, and there are two forms: GO and NGO. The oriented sheet has used with cold rolling and annealing process in a unified arrangement internal structure, so there is a very good single direction of the electrode properties. Non-oriented sheet has a random internal structure and in any direction uniform magnetic.
Application of oriented material is mainly used to the voltage gradually reduce of the transformer, range from power plants to ordinary users. Non-oriented material used for the rotating electrical equipment, such as automobiles and the alternator, range from a large rolling motor to a computer disk drive.
