The requirement of Silicon Steel:
1. Low Iron Loss, which is the most important value of the silicon steel quality. The lower iron steel, the higher brand number.
2. Under the strong magnetic induction, it is with high magnetic induction intensity, which can make motor and transformer core size and weight less, save the silicon steel sheet, copper wire and insulation material.
3. Smooth surface, and uniformity of thickness, which can improve filling coefficient of iron core.
4. Good blanking property, which is more important for producing mini and small motor.
5. Surface insulation film adhesion and good weldability, which can corrosion resistant and improve blanking property performance.
