According to the different silicon content, silicon steel can be divided into three categories: low silicon steel, medium silicon steel, and high silicon steel.
1. Low silicon steel: The silicon content is less than 1.8%, mainly used in motors, power transformers, and other equipment, with advantages such as low hysteresis and low iron loss.
2. Medium silicon steel: The silicon content is between 1.8% and 4.5%, which is the most common type of silicon steel. Mainly used in high-efficiency motors, transformers, power generation equipment, and other fields.
3. High silicon steel: The silicon content is greater than 4.5%, mainly used in high-performance electromagnetic devices such as high-frequency induction furnaces, high-speed generators, high-frequency transformers, etc., with high saturation induction flux density, high resistivity, low coercivity, and other characteristics.
