Hliníková doska anódy je oxidovaná, a na povrchu sa vytvorí tenká vrstva oxidu hlinitého s hrúbkou o 5 do 20 mikrónov, a tvrdý eloxovaný film môže dosiahnuť 60 do 200 mikrónov. Eloxovaný hliníkový plech zlepšuje jeho tvrdosť a odolnosť proti opotrebovaniu, až do 250-500 kg/mm2, má veľmi dobrú tepelnú odolnosť, tvrdý eloxovaný film má bod topenia až 2320 K, výborná izolácia, 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, atď.) can be anodized.

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