Silicon steel sheet classification
Silicon steel sheets can be divided into low silicon and high silicon according to their silicon content.
1. Low silicon wafer
Low silicon wafers contain less than 2.8% silicon, which has certain mechanical strength and is mainly used to manufacture motors, commonly known as silicon steel sheets for motors;
2. High silicon wafer
The silicon content of high silicon wafer is 2.8%-4.8%. It has good magnetic properties but is relatively brittle. It is mainly used to make transformer cores, commonly known as transformer silicon steel sheets. There is no strict boundary between the two in actual use, and high-silicon wafers are often used to manufacture large motors.
