SI

Electrical Steel is a specialized ferromagnetic alloy of iron and silicon (typically containing 0.5% to 6.5% Silicon) tailored to produce specific magnetic properties. It is the essential core material used in the manufacturing of electromagnetic devices such as motors, transformers, and generators. The addition of Silicon (Si) significantly increases the electrical resistivity of the steel, which reduces induced eddy currents and lowers hysteresis loss. This ensures that the material minimizes energy dissipation (heat loss) during the magnetization and demagnetization cycles, making electrical equipment more energy-efficient.

Non-Oriented (CRNO): Possesses uniform magnetic properties in all directions. Used primarily in Rotating Machinery (Motors, Generators).

Grain-Oriented (CRGO): Possesses superior magnetic properties in the rolling direction. Used primarily in Static Machinery (Transformers).
