Silicon steel sheet is an alloy, and iron-silicon alloy formed by adding a small amount of silicon (generally below 4.5%) to pure iron is called silicon steel. 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 contains a level of 2%-3.5% silicon. It has similar magnetic properties in all directions, the so-called isotropy. Grain-oriented electrical steel usually contains a level of 3% silicon and is processed in a way to develop ideal properties in the rolling direction. Cold-rolled non-grain-oriented steel (CRNGO) is less expensive than cold-rolled grain-oriented steel (CRGO). CRNGO can be used in cost-oriented applications with the inconstant direction of magnetic flux, such as electric motors and generators. CRGO is usually in coil form and has to be cut into laminations further, being used in transformer core applications, such as certain internal parts in audio output transformers.

Features of Silicon Steel
Great Electromagnetic Performance
The silicon steel comes with low iron loss and high magnetic
induction, especially HiB steel which has lower iron loss and
higher magnetic induction.

Good Shape
The material is often made in strips. Slight longitudinal and transverse thickness difference ensures a high lamination factor.

Insulating Coating
Uniform color, excellent insulative, high adhesion strength, high heat resistance, excellent processability, and superior corrosion resistance. Our silicon steel sheet is available in multiple insulating coating options, which have been reaching and RoHS certified that harmful matter content complies with domestic and overseas regulations on environmental protection.

Excellent Processability
Accessible to die-cut, with high dimensional accuracy.

Surface Quality
Our silicon steel features a smooth surface, without defects such as rust, rolling marks, holes, cold-lap,folds, bubbles, etc
