Electrical steel usually referring to 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 parallelto the rolling direction, has excellent magnetic properties in this direction including ow 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 random distribution of grain orientation and magnetic isotropy,is widely applicable to the motor industry.
Product features
Magnetic Properties
The magnetic properties of the product is featured by its low core loss, high permeability and excellent application performance.
Thickness Tolerance
The good thickness tolerance is characterized by small difference in thickness in a directionparalleto thedirection of rolling. small difference in
thickness in a directionperpendicular to the direction of rolling, and high lamination factor.
Processing Properties
The product is suitable for punching and cutting with excellent dimensional tolerance.
Insulation Coating
The insulation coating has small color deviation, good adhesiveness and excellent resistance to heating and corrosion with high insulation coating resistance.There are several types of insulation coating available for production .According to the test results performed by the professional inspection organizations,the contents of hazardous substances comply with all the prevailing international and domestic environment protection laws and regulations including EU RoHS and REACH regulations.
