Silicon steel, also known as "electrical steel", is a soft magnetic alloy of ferrosilicon with extremely low carbon content. The addition of silicon can not only increase the resistivity and maximum permeability of iron, but also reduce core loss (iron loss), coercivity, and magnetic aging. It is generally used in the iron cores of various motors and transformers, and is an indispensable and important soft magnetic alloy in the power, electronics and military industries.
