Native aluminium occurs in aluminium-rich rocks, in high-temperature hydrothermal tin-tungsten deposits and their alteration zones and in volcanic ash. Associated minerals include antimony, cadmium, copper, hematite, ilmenite, iron, jarosite, lead, magnetite, moissanite, pyrite, sulphur, tin and zinc (Mindat).


At the Getang Au-Sb deposit, Anlong county, Qianxi'nan, Guizhou, China, native aluminium is associated with copper, sulphur and jarosite (HOM).

There are two co-type localities, the Billeekh Intrusion and Dike OB-255, both in the Sakha Republic, Russia. Here native aluminium occurs in a gabbro-dolerite massif associated with zinc, tin, moissanite, lead, iron, copper, cadmium and antimony (HOM, Mindat).

At the Tolbachik volcano, Kamchatka Krai, Russia, native aluminium is associated with magnetite, ilmenite, hematite, pyrite and iron (HOM).
