Product Introduction
ultra-thin non-oriented and grain oriented electrical steel sheet for transformer core silicon steel coilElectrical 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.
The difference between oriented silicon steel and non-oriented silicon steel
Non-oriented silicon steel: ferrosilicon alloy with very low carbon content. In the deformed and annealed steel sheet, its grains are distributed randomly. The silicon content of the alloy is 1.5% to 3.0%, or the sum of the silicon and aluminum content is 1.8% to 4.0%. The products are usually cold-rolled plates or strips, which are mainly used to manufacture motors and generators. Oriented silicon steel: It has strong directionality, the lowest iron loss value in the rolling direction, the highest magnetic permeability, and a higher magnetic induction value under a certain magnetization field. The silicon content of oriented silicon steel is about 3%. It also requires a low content of oxide inclusions in the steel and must contain certain inhibitors (MnS, A1N).

Keywords: ultra-thin non-oriented and grain oriented electrical steel sheet
Non oriented fully processed steels are iron-silicon alloys with varying silicon contents and have similar magnetic properties in all directions in the plan of the sheet. They are principally used for motors, generators, alternators, ballasts, small transformers and a variety of other electromagnetic applications.
