Oriented Electrical Steel

Oriented electrical steel. with its easy magnetization direction parallel to the rolling direction, has excellenl magnetic properties in this direction including low core loss, high permeabdility and low magnetostriction and is widely used in the transformer industry.Further It can obtain lower core loss by domain refinement treatment.1
