ORNL's iron aluminides possess three properties that also make them ideal as heating elements. They are highly resistant to oxidation and corrosion, and they have electrical resistivities that are higher than many commercially available heating-element materials. Evaluation by a private vendor showed that iron aluminide heating elements do not burn up as fast as commercial heating elements. In one experiment, an ORNL-modified iron aluminide element lasted almost three times as long as the commercial one.
