EI Non-Oriented Cold Rolled Silicon Steel Low Frequency Transformer Permalloy Sheet Magnetic Lamination Core Cutting Welding

These components are manufactured from high-quality cold-rolled non-oriented silicon steel (CRNGO), specifically selected for its isotropic magnetic properties, which ensure consistent performance in alternating magnetic fields. Utilizing precision progressive die stamping, the material is cut into standard “E” and “I” shaped laminations. This process minimizes burrs and dimensional variation, allowing for tight stacking and a high lamination factor. Widely used as the core material for low to medium-frequency transformers, power adapters, and control transformers, these EI laminations offer an optimal balance of low core loss, high efficiency, and cost-effectiveness for general industrial applications.
