The electrical sheet for a laminated core is made of iron-silicon alloy and is divided into grain-oriented and non-grain-oriented materials. The starting material is manufactured as cold-rolled strip. It has special physical properties and belongs to the soft magnetic materials. Non-grain oriented electrical steel is classified by DIN EN 10106. A large number of standard grades exist for use in electrical systems, motors and machines.
