Abstract
A method is provided for producing a magnetic core. A semi-processed cold rolled electrical steel is provided comprising .005 ≦ Tin ≦ .09% .0 < Carbon ≦ 0.050% .10 ≦ Manganese ≦ 1.00% .005 ≦ Phosphorus ≦ .120% .0 < Sulfur ≦ .010% .50 ≦ Silicon ≦ 2.50% .01 ≦ Aluminum ≦ 1.60% .0 ≦ Antimony < .02% Iron—at least substantial portion of balance. The semi-processed electrical steel is stamped to create stamped parts. The stamped parts are assembled and annealed after the stamping to form the magnetic core.
