Thin-gauge efficient non-oriented electrical steel and preparation method and application thereof

The invention relates to thin-gauge efficient non-oriented electrical steel and a preparation method and application thereof, and belongs to the technical field of steel preparation. The electrical steel comprises the following chemical components in percentage by mass: 1.0%-2.4% of Si, 0.1%-0.8% of Mn, less than or equal to 0.003% of S, 0.2%-1.0% of Al, 0.01%-0.2% of Sn or Sb and the balance of Fe and inevitable impurities. By controlling the content of the components of the electrical steel, such as Si, Mn, Al, Sn or Sb elements, the electromagnetic performance is improved, so that the electrical steel can have lower iron loss, the iron loss P1.5/50 is less than or equal to 3.0 W/kg and better magnetic induction performance, the magnetic induction strength B5000 is greater than or equal to 1.70 T without performing hot-rolled coil normalizing or other heat treatment processes during preparation, and on the premise that the performance requirement of the electrical steel is met, the electrical steel can be u
