Aluminijasta plošča anode je oksidirana, in na površini se tvori tanka plast aluminijevega oksida z debelino 5 do 20 mikronov, in trda anodizirana folija lahko doseže 60 do 200 mikronov. Anodizirana aluminijasta plošča izboljša njegovo trdoto in odpornost proti obrabi, do 250-500 kg/mm2, ima zelo dobro toplotno odpornost, trda anodizirana folija ima tališče do 2320 K, odlična izolacija, 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 (such as aluminum, magnesium and their alloys, itd.) can be anodized.

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