▎ 摘  要

NOVELTY - A electric steel comprises least one functional layer (4) comprising at least partially of a ferromagnetic material and at least one additional layer (8) comprising at least partially of a non-magnetizable material. The layers (4) and (8) are connected to one another by an adhesive bond (12) with atomic diffusion (14). USE - Electrical steel used as strip e.g. steel sheets (claimed). Uses include but are not limited to generators, transformers, electric motors, magnetic core in the form of stator, rotors, relays, switches, contactor, chokes, ignition coil, electricity meter, controllable deflection magnets, iron core, etc. ADVANTAGE - The electrical steel has improved magnetic property, mechanical property, energy efficiency, thermal conductivity, reduced hysteresis loss, reduced core loss, reduced internal stress, enables operation at high thermal loads, and is used in high frequency and speed. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the manufacturing steel strip in the form of steel sheet.
