2.Related introduction

The iron-silicon alloy containing 0.5-4% of silicon has lower hysteresis loss and higher resistivity than pure iron and can be used under a high magnetic field of power frequency and audio frequency. To reduce the eddy current loss, the iron-silicon alloy must be hot-rolled into a 0.35 or 0.5 mm thick sheet, punched into a certain shape, and laminated for use, so it is generally called a silicon steel sheet. It is used the most in the power industry, so it is often called electrical steel.

According to the frequency of use, the thickness of the belt is also different (usually 0.02~0.2 mm). In the power industry, Fe-Si alloys are mainly used in motors and transformers. In the electronics industry, they are mainly used in power transformers, audio transformers, pulse transformers, etc.
