Electrical steel, also called lamination steel, silicon electrical steel, silicon steel or transformer steel, is a material used to produce certain magnetic cores, such as stators and rotors in transformers and motors. Electrical steel is also an indispensable material for the power, electronics and military industries.

Non-oriented electrical steel usually has a silicon level of 2 to 3.5% and has similar magnetic properties in all directions, which makes it isotropic. It is less expensive and is used in applications where the direction of magnetic flux is changing, such as electric motors and generators. It is also used when efficiency is less important or when there is insufficient space to correctly orient components to take advantage of the anisotropic properties of grain-oriented electrical steel.


Silicon steel is the most important magnetic material in industrial applications. The general applications include volt relays or pulse transformers from the generator, automotive, and transformer sectors.
