Silicon Steel

Silicon steel/Electrical steel

Electrical steel usually referred to as cold-rolled electrical steel, can be divided into two major categories including grain-oriented electrical steel and non-oriented electrical steel. 

Grain-oriented electrical steel, with its easy magnetization direction parallel to the rolling direction, has excellent magnetic properties in this direction including low core loss, high permeability, and low magnetostriction, and is widely used in the transformer industry. Further, it can obtain lower core loss by domain refinement treatment. Meanwhile, non-oriented electrical steel, featured by a random distribution of grain orientation and magnetic isotropy, is widely applicable to the motor industry.

We have Silicon Steel Coil in non oriented and Oriented type, We produce all kinds of EI HID silicon steel sheet,commonly used in barretter,rotor of motor.

Material are 23Q110 30Q120 35Q145 35WW230 35WW250 35WW270. ASTM 36F145 36F158 36F168 36F180 M80050A.

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

We believe we will be helpful for the customer to take advantage of the characteristics of our products so as to design and manufacture more excellent electric and electrical products.
