Placa de aluminiu a anodului este oxidată, iar la suprafaţă se formează un strat subţire de oxid de aluminiu cu o grosime de 5 la 20 microni, iar filmul anodizat dur poate ajunge 60 la 200 microni. Placa din aluminiu anodizat ii imbunatateste duritatea si rezistenta la uzura, până la 250-500 kg/mm2, are o rezistenta foarte buna la caldura, filmul anodizat dur are un punct de topire de până la 2320K, izolare excelenta, 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, etc.) can be anodized.

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