Anoda alumīnija plāksne ir oksidēta, un uz virsmas veidojas plāns alumīnija oksīda slānis, kura biezums ir 5 uz 20 mikroni, un cietā anodētā plēve var sasniegt 60 uz 200 mikroni. Anodētā alumīnija plāksne uzlabo tās cietību un nodilumizturību, līdz 250-500 kg/mm2, ir ļoti laba karstumizturība, cietās anodētās plēves kušanas temperatūra ir līdz 2320K, lieliska izolācija, and breakdown resistance The voltage is as high as 2000V, which enhances the anti-corrosion performance. It will not corrode for thousands of hours in ω=0.03NaCl salt spray.

There are a lot of micropores in the thin oxide film layer, which can adsorb various lubricants, suitable for the manufacture of engine cylinders or other wear-resistant parts; the film micropores have strong adsorption capacity and can be colored into various beautiful and bright colors. Non-ferrous metals or their alloys (piemēram, alumīnijs, magnesium and their alloys, utt.) can be anodized.

Anodized aluminum sheets are widely used in mechanical parts, aircraft auto parts, precision instruments and radio equipment, arhitektoniskā apdare, machine casings, lamps and lighting, consumer electronics, handicrafts, household appliances, interior decoration, signs, furniture, automotive decoration and other industries.
