GENERAL INFO
          History

Discovered in 1825 by Hans Christian Oersted in Coepnhagen, Denmark.  The name is derived from Latin word "alumen" for the mineral alum.

          Uses
  • Alloys used in cans, foils, building materials.  Also used in aerospace materials.
  • Oxide form used in jewelry, glass, and refractory industries.
  • Used in steel making as deoxidizer and degasifier.  Also aids in fine grain formation.
  • Used in nitriding steels due to the very hard aluminum nitride formed with Nitrogen.
