Silicon steel is also called "electrical steel", is a very low carbon ferrosilicon soft magnetic alloy. The addition of silicon can not only increase the resistivity and maximum permeability of iron, on the other hand, it can also reduce the core loss (iron loss), coercivity, magnetic aging. It is generally used in the iron cores of various motors and transformers, and is an indispensable soft magnetic alloy in the power, electronics and military industries.

(1) According to the production process: can be divided into hot-rolled and cold-rolled silicon steel, hot-rolled silicon steel is low availability, large energy loss, has gradually begun to be phased out. Cold-rolled silicon steel is divided into oriented silicon steel and non-oriented silicon steel according to the internal grain orientation.

(2) According to the different silicon content, electrical steel is divided into low silicon chips (low grade) and high silicon chips (high grade). Low silicon sheet has a certain mechanical strength, mainly used in the manufacture of motor, commonly known as motor silicon steel sheet; High silicon is good magnetic, but more brittle, mainly used in the manufacture of transformer core, commonly known as transformer silicon steel sheet.
