Aluminium (Al) ke ntho ea tšepe e ngata ka ho fetisisa karolong e ka holimo ea Lefatše. Ha e kopantsoe le oksijene le hydrogen, e etsa bauxite, e leng aluminium e sebelisoang haholo merafong ea ore. Karohano ea pele ea aluminium chloride ho tloha aluminium ea tšepe e ne e le 1829, empa tlhahiso ea khoebo ha ea ka ea qala ho fihlela ka 1886. Aluminium ke tšepe e tšoeu ea silevera, e thata, e bobebe e nang le matla a itseng a 2.7. Ke conductor e ntle ea motlakase 'me e thibela ho bola haholo. Ka lebaka la litšobotsi tsena, e fetohile tšepe ea bohlokoa.Motsoako oa aluminiume na le matla a maqhama a bobebe 'me ka hona e sebelisoa liindastering tse fapaneng tse fapaneng.

 
Tlhahiso ea alumina e ja 90% ea tlhahiso ea lefats'e ea bauxite. Tse ling kaofela li sebelisoa liindastering tse kang li-abrasives, lisebelisoa tse refractory le lik'hemik'hale. Bauxite e boetse e sebelisoa tlhahisong ea samente e phahameng ea alumina, e le sesebelisoa sa ho boloka metsi kapa e le sesebelisoa sa indasteri ea peterole bakeng sa ho roala lithupa le li-fluxes, hape e le phallo ea ho etsa litšepe le li-ferroalloys.

Tšebeliso ea aluminium e kenyelletsa lisebelisoa tsa motlakase, likoloi, likepe, tlhahiso ea lifofane, lisebelisoa tsa tšepe le lik'hemik'hale, kaho ea malapeng le ea indasteri, ho paka (foil ea aluminium, makotikoti), lisebelisoa tsa kichineng (tableware, lipitsa).

 
Indasteri ea aluminium e qalile nts'etsopele ea thekenoloji ea ho tsosolosa lisebelisoa tse nang le aluminium content 'me e thehile setsi sa eona sa pokello. E 'ngoe ea likhothatso tse ka sehloohong bakeng sa indasteri ena esale e le phokotso ea tšebeliso ea matla, e hlahisa tone e le' ngoe ea aluminium e fetang tone e le 'ngoe ea aluminium ea mantlha. Sena se kenyelletsa ho hlahisa metsi a 95% a aluminium ho tloha bauxite ho boloka matla. Tone e 'ngoe le e 'ngoe ea aluminium e sebelisoang hape e bolela ho boloka lithane tse supileng tsa bauxite. Australia, 10% ea tlhahiso ea aluminium e tsoa linthong tse nchafalitsoeng.
