1. A method of processing an iron cobalt alloy, comprising:
pre-annealing a sheet of an iron cobalt alloy at a pre-anneal temperature, wherein the pre-anneal temperature is about 770° C. to about 805° C. for period between about 1 minute and about 10 minutes;
thereafter, cutting a component from the sheet;
thereafter, heat-treat annealing the component at a treatment temperature for a treatment period of about 1 minute to about 10 minutes, wherein the treatment temperature is about 845° C. to about 870° C.; and
thereafter, exposing the component to oxygen at an oxidizing temperature to form an insulation layer on a surface of the component.
