Silicon Steel
Silicon steel, also known as electrical steel, silicon electrical steel, lamination steel, relay steel, or transformer steel is specialty steel with silicon added to it, which improves its electrical resistivity and magnetic properties, and reduces hysteresis loss. This steel is ideal for various electrical applications where electromagnetic fields are of great importance, such as in transformers, magnetic coils and electrical motors.
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. Small longitudinal and transverse thickness difference ensures high lamination factor.
Insulating Coating
Uniform color, excellent insulativity, high adhesion strength, high heat resistance, great processability and superior corrosion resistance. Our silicon steel sheet is available in multiple insulating coating options, which have been REACH and RoHS certified that harmful matter content complies with domestic and overseas regulations on environmental protection.
Excellent Processability
Easy to die cut, with high dimensional accuracy.
Surface Quality
Our silicon steel features smooth surface, without defects such as rust, rolling marks, holes, cold-lap, folds, bubbles, etc.
