35WW270 is a non-grain oriented electrical steel with a nominal thickness of 0.35mm. The "W" indicates a wide width tolerance, and the "270" denotes a guaranteed maximum core loss of 2.70 W/lb at 1.5T and 60Hz. This grade is engineered for superior electromagnetic performance, specifically low core loss at high frequencies.
Its unique alloy composition minimizes energy dissipation from hysteresis and eddy currents, making it ideal for high-efficiency transformers, motors, generators, and power distribution equipment. The low carbon content further enhances performance by reducing core heating during operation.
