Letlapa la aluminium la anode le na le oxidized, 'me lera le tšesaane la aluminium oxide e thehoa holim'a metsi ka botenya ba 5 ho 20 microns, 'me filimi e thata ea anodized e ka fihla 60 ho 200 microns. Letlapa la aluminium ea anodized le ntlafatsa ho thatafala ha lona le ho hanyetsa ho apara, ho fihlela 250-500 kg/mm2, e na le khanyetso e ntle haholo ea mocheso, filimi e thata ea anodized e na le ntlha ea ho qhibiliha ho fihlela ho 2320K, insulation e babatsehang, 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 (joalo ka aluminium, 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, mokhabiso oa kaho, machine casings, lamps and lighting, consumer electronics, handicrafts, household appliances, interior decoration, signs, thepa ea ka tlung, automotive decoration and other industries.
