Product Description

Product Description

 

Silicon Steel Coils 0.23/0.27/0.30 CRGO Electrical Steel for Transformer Lamination Iron Core
Silicon steel, also known as silicon steel sheet or electrical steel, is a ferrosilicon soft magnetic alloy with a very low carbon content, typically containing 0.5% to 4.5% silicon. The addition of silicon enhances the resistivity and maximum permeability of iron, significantly reducing coercivity, iron loss, and magnetic aging.

The Difference Between Oriented Silicon Steel and Non-Oriented Silicon Steel
Non-Oriented Silicon Steel: This is a ferrosilicon alloy with an extremely low carbon content. In deformed annealed steel plates, the grains are distributed randomly. The silicon content ranges from 1.5% to 3.0%, or the combined silicon and aluminum content ranges from 1.8% to 4.0%. These products are typically cold-rolled sheets or strips, mainly used in the manufacturing of motors and generators.

Superior Quality Grain Oriented Flat-Rolled Electrical Steel
This premium cold-rolled electrical steel contains between 2.9% to 3.5% silicon (Si) and features a meticulously regular and directional crystal structure. Grain Oriented Electrical Steel is an essential soft magnetic material in the power industry, prominently utilized in transformers, rectifiers, reactors, and large motors, among other high-demand applications.
