Aluminiyamu mbale ya anode ndi oxidized, ndi wosanjikiza woonda wa aluminium okusayidi aumbike pamwamba ndi makulidwe a 5 ku 20 ma microns, ndipo filimu yolimba ya anodized imatha kufika 60 ku 200 ma microns. Chovala cha aluminiyamu cha anodized chimapangitsa kuuma kwake komanso kukana kuvala, mpaka 250-500 kg/mm2, ali ndi kutentha kwabwino kwambiri, filimu yolimba ya anodized ili ndi malo osungunuka mpaka 2320K, zabwino kwambiri zotsekera, ndi kukana kuwonongeka Magetsi ndi okwera ngati 2000V, zomwe zimawonjezera ntchito ya anti-corrosion. Sidzawononga kwa maola masauzande ambiri mu ω=0.03NaCl kupopera mchere.
Pali ma micropores ambiri mu filimu yopyapyala ya oxide, amene amatha adsorb mafuta osiyanasiyana, oyenera kupanga masilindala a injini kapena zida zina zosavala; ma micropores amakanema ali ndi mphamvu zotsatsa zolimba ndipo amatha kukhala ndi mitundu yosiyanasiyana yokongola komanso yowala. Zitsulo zopanda chitsulo kapena ma alloys awo (monga aluminiyamu, Magnesium ndi olosera zawo, ndi zina.) ikhoza kuvomerezeka.
Mapepala a aluminiyamu anodized amagwiritsidwa ntchito kwambiri pamakina, magalimoto a ndege, Zida zowongolera ndi zida za radio, zokongoletsa zomangamanga, Makina Makina, nyali ndi kuyatsa, Magetsi amagetsi, kupindika, zida zapakhomo, Zokongoletsa zamkati, Zizindikiro, mipando, zokongoletsera zamagalimoto ndi mafakitale ena.
