A piastra d'aluminiu di l'anodu hè oxidatu, è una fina capa di oxidu d'aluminiu hè furmatu nantu à a superficia cù un grossu di 5 à 20 microni, è a film anodized duru pò ghjunghje 60 à 200 microni. A piastra d'aluminiu anodizatu migliora a so durezza è a resistenza à l'usura, finu à 250-500 kg/mm2, hà assai bona resistenza à u calore, u film anodized duru hà un puntu di fusione sin'à 2320K, eccellente insulazione, 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 (cum'è l'aluminiu, magnesium and their alloys, ecc.) can be anodized.

Anodized aluminum sheets are widely used in mechanical parts, aircraft auto parts, precision instruments and radio equipment, decoru architetturale, machine casings, lamps and lighting, consumer electronics, handicrafts, l'apparecchi di casa, interior decoration, segni, mobili, automotive decoration and other industries.
