As an important indicator of quality, each country divides the grade by the iron loss value. The lower the iron loss, the higher the grade and the higher the quality.B. High magnetic induction strength. Under the same magnetic field, the silicon steel sheet with high magnetic sensitivity can be obtained. The volume and weight of the iron core of the motor or transformer made by it are relatively small, which can save silicon steel sheet, copper wire and insulating materials, etc.C. High stacking coefficient. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, which improves the stacking coefficient of the iron core.D. Good punching property. This is more important for manufacturing small and micro motor iron cores.E. The surface has good adhesion and weldability to the insulating film.
