Alumiinium on keemiline element järjenumbriga 13.

Tal on üks stabiilne looduslik isotoop massiarvuga. Radioaktiivne isotoop massiarvuga 26 tekib looduses kosmiliste kiirte mõjul.

Alumiinium on hõbevalge metall tihedusega 2,7 g/cm³ ja sulamistemperatuuriga 660 °C.

Alumiiniumi keemilise aktiivsuse tõttu teda looduses lihtainena ei esine.

Alumiinium reageerib paljude lihtainete ja hapetega. Hapetest tõrjub ta välja vesinikku ning tekib sool.

Amfoteersuse tõttu reageerib alumiinium ka leelistega, tõrjudes nende lahustest vesinikku välja ja moodustades aluminaate.

Kõigis püsivamates ühendites on alumiiniumi oksüdatsiooniaste +3. Alumiiniumoksiid on amfoteerne oksiid.

Alumiiniumi saadakse boksiidist. Alumiiniumi sulatus on üks kõige energiamahukamaid tootmisi. Sellepärats rajati alumiiniumi tootmist tehaseid hüdroenergiajaamade lähedusse. Tänapäeval rajatakse tehaseid rohkem sadamate lähedale.
