Ang aluminyo plate ng anode ay oxidized, at isang manipis na layer ng aluminyo oksido ay nabuo sa ibabaw na may isang kapal ng 5 sa 20 mga micron, at ang hard anodized film ay maaaring maabot 60 sa 200 mga micron. Ang anodized aluminyo plate ay nagpapabuti sa kanyang katigasan at paglaban sa pagsusuot, hanggang sa 250-500 kg/mm2, ay may napakahusay na paglaban sa init, ang hard anodized film ay may melting point na hanggang 2320K, mahusay na pagkakabukod, 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 (tulad ng aluminyo, magnesium and their alloys, atbp.) can be anodized.

Anodized aluminum sheets are widely used in mechanical parts, aircraft auto parts, precision instruments and radio equipment, dekorasyon ng arkitektura, machine casings, lamps and lighting, consumer electronics, handicrafts, household appliances, interior decoration, signs, mga kasangkapan sa bahay, automotive decoration and other industries.
