1. According to its silicon content, it can be divided into low silicon and high silicon.
Low silicon wafer contains less than 2.8% silicon, it has certain mechanical strength, it is mainly used to make motors, commonly known as motor silicon steel sheet; high silicon wafer contains 2.8%-4.8% silicon, it has good magnetic properties, but it is brittle, mainly used Used to manufacture transformer cores, commonly known as transformer silicon steel sheets. There is no strict limit between the two in actual use, and high silicon wafers are often used to manufacture large motors.
2. According to the production and processing technology, it is divided into: hot rolling and cold rolling.
Cold rolling can be divided into two types: non-oriented and oriented. Cold-rolled sheets have uniform thickness, good surface quality, and high magnetic properties. Therefore, with the development of industry, hot-rolled sheets have a tendency to be replaced by cold-rolled sheets.
