Anodo aliuminio plokštė yra oksiduota, o ant paviršiaus susidaro plonas aliuminio oksido sluoksnis, kurio storis 5 į 20 mikronų, ir kieta anoduota plėvelė gali pasiekti 60 į 200 mikronų. Anoduota aliuminio plokštė pagerina jos kietumą ir atsparumą dilimui, iki 250-500 kg/mm2, turi labai gerą atsparumą karščiui, kietos anoduotos plėvelės lydymosi temperatūra yra iki 2320K, puiki izoliacija, 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, ir tt) can be anodized.

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