1, can aluminum alloy rust? Under normal circumstances, aluminum alloy will not rust, because it contains aluminum, aluminum has a strong oxidation resistance, can form a dense alumina film to prevent further oxidation and corrosion of aluminum alloy. However, if the aluminum alloy surface is scratched or damaged, it will destroy the aluminum oxide film, causing the aluminum alloy to begin to rust, so it is very important to maintain the integrity and cleanliness of the aluminum alloy surface.
2, once the aluminum alloy rusts, it is generally due to the influence of oxidation, corrosion and other factors on the surface of the aluminum alloy, resulting in oxidation and rust on the surface.
