Abstract
In the manufacture of a silicon-containing iron sheet for electrical applications consisting of 0.1-8% by weight Si, optionally up to 1% by weight Al, remainder iron and unavoidable impurities, iron sheet is made by electrodeposition, and silicon or a silicon-containing material is incorporated in the electro-deposited iron sheet. The silicon-containing material may be included in the electrolyte, becoming embedded during the electro-deposition in the iron sheet. The method can be performed without a step of thickness reduction of the iron sheet made by electro-deposition. The sheet is annealed to homogenize the silicon content.
