Due to the production needs of the product, we usually oxidize the surface of the aluminum alloy. Does the oxidized aluminum alloy have conductive properties?

The answer is non-conductive, oxidation is on the surface of the aluminum alloy shell, generate a layer of dense oxide film, the composition of this layer of oxide film is alumina Al203, this layer of oxide film, itself is non-conductive, if you want to finish oxidation, so that the product has conductive performance, we generally need to do passivation treatment, the so-called passivation treatment, That is, the surface of the aluminum alloy contains a complex agent under the condition of generating a stable compound, and with its film-forming stability, the formation of a firm, dense and corrosion-resistant passivation film. Passivated film, colorless, bright, strong corrosion resistance. Or in the part that needs to conduct electricity, remove this layer of oxide film, and you can conduct electricity in the place where the product needs to conduct electricity.
