Álplata rafskautsins er oxað, og þunnt lag af áloxíði myndast á yfirborðinu með þykkt á 5 til 20 míkron, og harða anodized filman getur náð 60 til 200 míkron. Anodized álplatan bætir hörku og slitþol, upp í 250-500 kg/mm2, hefur mjög góða hitaþol, harða anodized filman hefur bræðslumark allt að 2320K, framúrskarandi einangrun, 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 (eins og ál, magnesium and their alloys, o.s.frv.) can be anodized.

Anodized aluminum sheets are widely used in mechanical parts, aircraft auto parts, nákvæmnistæki og fjarskiptabúnað, byggingarlistarskreyting, machine casings, lamps and lighting, consumer electronics, handicrafts, heimilistæki, interior decoration, merki, húsgögn, automotive decoration and other industries.
