Aluminum (Al) shine mafi yawan sinadarin ƙarfe a cikin ɓawon ƙasa. Haɗe da oxygen da hydrogen, yana samar da bauxite, wanda shine mafi yawan amfani da aluminum wajen haƙar ma'adinai. Rabuwar farko na aluminum chloride daga aluminium na ƙarfe ya kasance a cikin 1829, amma samar da kasuwanci bai fara ba har sai 1886. Aluminum farin azurfa ne, mai wuya, ƙarfe mara nauyi tare da takamaiman nauyi na 2.7. Yana da kyakkyawan jagorar wutar lantarki kuma mai jure lalata. Saboda waɗannan halaye, ya zama ƙarfe mai mahimmanci.Aluminum gamiyana da ƙarfin haɗin haske don haka ana amfani dashi a cikin masana'antu iri-iri.

 
Samar da alumina yana cinye kashi 90% na samar da bauxite na duniya. Sauran ana amfani da su a cikin masana'antu kamar su abrasives, kayan da aka lalata, da sinadarai. Ana kuma amfani da Bauxite wajen samar da babban siminti na alumina, a matsayin wakili mai riƙe da ruwa ko kuma a matsayin mai haɓakawa a cikin masana'antar mai don shafa sandunan walda da ɗigon ruwa, kuma a matsayin juzu'i don yin ƙarfe da ferroalloys.
