0.27mm Transformer Core Sheets

The 0.27mm Transformer Core Sheets are a professional-grade grain-oriented electrical steel product purpose-engineered for the full spectrum of transformer core manufacturing. Conforming to IEC 60404-8-7, IS 649, and ASTM A876 standards, these sheets offer documented, traceable magnetic performance aligned with M4 Grade classification.
The 0.27mm gauge is the industry's most widely adopted CRGO thickness, trusted by transformer manufacturers globally for its consistent processability, well-established performance benchmarks, and broad compatibility with existing punching and stacking tooling. Available in all three length formats — regular, semi jumbo, and jumbo — to match your specific core design. Laser scribing and stress-relief annealing options available. Mill test reports and certificates of conformance provided on request.
