Product Introduction
Electrical steel, also known as silicon steel, is a ferrosilicon soft magnetic alloy steel with very low carbon content, usually containing 0.5% to 4.5% silicon. The addition of silicon can increase the resistivity and maximum permeability of iron, and reduce the coercivity, iron loss and magnetic aging.
