Oriented Grain Silicon Steel Coils High Magnetic Inductance For Sale At Wholesale Price

1.Definition: 

Silicon alloy steel with silicon content of 1.0~4.5% and carbon content of less than 0.08% is called silicon steel. It has the characteristics of high permeability, low coercivity, and high resistivity, so the hysteresis loss and eddy current loss are small. It is mainly used as a magnetic material in motors, transformers, electrical appliances and electrical instruments.

2.Category:

According to the manufacturing process and use, electrical steel is divided into three categories: hot-rolled silicon steel, cold-rolled electrical steel and special-purpose silicon steel.

3.Performance Requirements:

1. Low iron loss, which is the most important indicator of the quality of silicon steel sheet. Countries classify grades according to the value of iron loss, and the lower the iron loss, the higher the grade.

2. The magnetic induction intensity is high under a strong magnetic field, which reduces the volume and weight of the core of the motor and transformer, and saves silicon steel sheets, copper wires and insulating materials.

3. The surface is smooth, flat and uniform in thickness, which can improve the filling coefficient of the core.

4. Good punching performance, which is more important for the manufacture of micro and small motors.

5. The adhesion and weld ability of the surface insulating film are good, which can prevent corrosion and improve the punching property.
