陽極のアルミ板が酸化している, 表面に酸化アルミニウムの薄い層が厚さで形成されます。 5 に 20 ミクロン, 硬質陽極酸化皮膜が到達できる 60 に 200 ミクロン. アルマイト処理されたアルミニウムプレートにより、硬度と耐摩耗性が向上します, まで 250-500 kg/mm2, 非常に優れた耐熱性を持っています, 硬質陽極酸化皮膜の融点は2320Kに達します。, 優れた断熱性, 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 (アルミニウムなどの, magnesium and their alloys, 等) can be anodized.

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