CRGO Grain‑Oriented Silicon Steel Laminated Transformer Core

Cold Rolled Grain Oriented (CRGO) Silicon Steel is specifically designed for transformer cores. It features high magnetic permeability along the rolling direction, resulting in low iron loss and low magnetizing current. The material allows for efficient energy conversion with minimal noise and no magnetic flux leakage. Available in various thicknesses (0.23mm, 0.27mm, 0.30mm, 0.35mm) and can be supplied as tape-wound cores or laminations.
