Technological Development of 6.5wt%Si Electrical Steel Production

6.5wt%Si electrical steel has a wide application in electrical and electronic devices based on its excellent soft magnetic properties. However, it is very hard to prepare thin sheets of this material by conventional rolling methods, because of its obvious brittleness at room temperature. In order to avoid brittleness at high silicon content, different technological development of preparations of 6.5wt%Si electrical steel are illustrated in this work.
