Patent ID: 8778100

Claim:
A method for the production of a magnetic strip of a semi-hard magnetic crystalline alloy, wherein the strip has a magnetic easy axis running axially parallel to a transverse axis of the strip, comprising: smelting of a semi-hard magnetic alloy; casting of the smelted alloy to form an ingot; hot forming of the ingot into strip material; cold forming of the strip material substantially to a thickness of the strip to be produced, by rolling the strip material along a direction of rolling; annealing the strip material in a magnetic field, wherein the direction of the magnetic field is axially parallel to a transverse axis of the strip material and wherein the transverse axis of the strip material is at right-angles to the direction of rolling; producing a narrow strip by reducing a width of the rolled strip material substantially to a width of the strip to be produced, wherein the width of the strip material and the width of the narrow strip are arranged at right-angles to the direction of rolling; and separating the strip to be produced from the narrow strip along the width of the narrow strip, thereby producing a separated strip having a length substantially corresponding to a length of the strip to be produced and having a width substantially corresponding to the width of the strip to be produced.
