Mae plât alwminiwm yr anod wedi'i ocsidio, ac mae haen denau o alwminiwm ocsid yn cael ei ffurfio ar yr wyneb gyda thrwch o 5 i 20 micronau, a gall y ffilm anodized caled gyrraedd 60 i 200 micronau. Mae'r plât alwminiwm anodized yn gwella ei galedwch a'i wrthwynebiad gwisgo, hyd at 250-500 kg/mm2, mae ganddi wrthwynebiad gwres da iawn, mae gan y ffilm anodized caled bwynt toddi o hyd at 2320K, inswleiddio ardderchog, 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, etc.) can be anodized.

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