1, the iron loss is low, this is the silicon steel sheet quality most important index.
Each country is divided according to the iron loss value, the lower the iron loss, the higher the grade.
2, strong magnetic induction (magnetic susceptibility) high, which makes the motor and transformer core volume and weight reduction, saving silicon steel, copper wire and insulating materials.
3, smooth surface, flat and uniform thickness, can improve the filling coefficient of iron core.
4, good punching, for the manufacture of miniature, small motor is more important. 5, the surface insulation film adhesion and weldability is good, can prevent corrosion and improve the punching performance.
