Abstract : This invention provides a process for preparing a nonflammable insulating sheath on a metal conductor wherein the sheath does not shed, slough off, wipe off, or crack when said conductor is flexed or bent comprising the steps of adding impurities to a metal electrical conductor, zonally annealing said conductor and rectifying said conductor metallurgically by exposing said conductor to a magnetic or electrical field. The process of this invention provides a conductor sheathing that does not burn, smoke, smoulder, yield toxic fumes or crack during bending or flexing. More specifically, this invention provides a process for preparing an inorganic insulating coating on an electrical conductor comprising adding an impurity selected from the group consisting of iron oxide, iron sulfide, iron telluride, iron sellenide, molybdenum sulfide, chromium sulfide, cobalt oxide, cobalt telluride, cobalt sellenide, nickel telluride, nickel sellenide and insulating coating that, after subsequent processing, does not burn, smoke, smoulder, yield toxic fumes, or crack during bending or flexing to the melt of a metal electrical conductor, zonally annealing said conductor, and rectifying said conductor to a magnetic or electrical field.
