0.27mm M4 Grade CRGO Core

The 0.27mm M4 Grade CRGO Core product line represents the complete material offering for transformer core manufacturing under the M4 specification — the world's most widely used CRGO grade. Whether your production requires sheets in regular, semi jumbo, or jumbo lengths, or continuous coil form for slitting and stamping, this product line covers all supply formats under a single, consistent material specification.
With 0.27mm thickness and M4 Grade magnetic characteristics, this CRGO core material is suited for a broad range of transformer efficiency targets — delivering defined maximum core loss (W/kg) and minimum magnetic flux density (T) values that design engineers can rely upon across production batches. All supply forms are available with laser scribing treatment for domain refinement (reducing core losses by 5–15%) and with or without stress-relief annealing.
