Silicon steel
Silicon steel is an iron‑silicon soft‑magnet alloy with silicon added to reduce core loss and boost magnetic permeability. Commonly used in power grid, new‑energy vehicle and electrical equipment fields.
Oriented Electrical Steel
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.
