CRGO Grain‑Oriented Electrical Steel for Power Transformer

Grain-oriented silicon steel (GOES) is a soft magnetic polycrystalline metallic alloy specifically engineered for transformer cores. It features high magnetic permeability and low core loss along the rolling direction, significantly improving energy efficiency in electrical transformers. Available in various grades (e.g., UI series) with different thicknesses and coating types.
