0.27mm CRGO Lamination Core Sheets

The 0.27mm CRGO Lamination Core Sheets are precision-grade grain-oriented silicon steel sheets specifically processed and prepared for transformer core lamination assemblies. Designed to be punched, sheared, or laser-cut into E-I, L, T, U, or step-lap lamination profiles, these sheets serve a wide range of transformer types and power ratings.
Manufactured from M4 Grade CRGO material, these sheets exhibit excellent stacking factor values (typically ≥ 0.96), ensuring the assembled core approaches theoretical iron fill density with minimal air gaps — directly contributing to lower no-load losses, reduced magnetizing current, and improved overall transformer efficiency. Available in multiple length ranges — regular, semi jumbo, and jumbo — to suit different core sizes, with optional annealing and laser scribing treatments.
