O le ipu alumini o le anode ua oxidized, ma o se vaega manifinifi o le alumini oxide ua faia i luga ma se mafiafia o 5 ia 20 microns, ma e mafai ona o'o atu le ata tifaga anodized malo 60 ia 200 microns. O le anodized alumini ipu faʻaleleia lona maaa ma ofuina teteʻe, i luga 250-500 kilokalama/mm2, e lelei tele le tete'e vevela, o le ata tifaga anodized malo o loʻo i ai se mea faʻafefeteina e oʻo atu i le 2320K, fa'aeseese lelei, 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 (pei ole alumini, magnesium and their alloys, ma isi.) can be anodized.

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