M15 Silicon Steel Coil

Silicon alloy steel containing 1.0 to 4.5% silicon and less than 0.08% carbon is called silicon steel. It has the characteristics of high magnetic permeability, low coercivity, and large resistivity, so the hysteresis loss and eddy current loss are small. Mainly used as magnetic materials in motors, transformers, electrical appliances and electrical instruments. In order to meet the needs of punching and shearing when manufacturing electrical appliances, a certain degree of plasticity is also required. In order to improve the magnetic induction performance and reduce hysteresis loss, the content of harmful impurities is required to be as low as possible, and the plate shape is required to be smooth and the surface quality is good.

1. Low iron loss, which is the most important indicator of the quality of silicon steel sheets. Countries all classify grades according to the iron loss value. The lower the iron loss, the higher the grade.
2. The magnetic induction intensity (magnetic induction) is high under a strong magnetic field, which reduces the size and weight of the cores of motors and transformers, saving silicon steel sheets, copper wires, and insulating materials.
3. The surface is smooth, flat and uniform in thickness, which can improve the filling factor of the iron core.
4. Good punching properties are more important for manufacturing micro and small motors.
5. The surface insulating film has good adhesion and weldability, can prevent corrosion and improve punching properties.
