What factors will affect the service life of industrial aluminum profile products?
1, whether the industrial aluminum profile has been surface treated. Generally, the surface of industrial aluminum profile will be anodized, but there are also cases where it is not treated. The service life of surface anodizing treatment is longer than that of substrate, because the artificially formed oxide film is much more uniform, dense and thicker than the naturally formed oxide film in the air, which can well block the air, and the hard oxide film is very wear-resistant.
2, the use of places, in the open air environment and indoor service life is also different. There are also some special industrial aluminum profiles that will be used in water or in more corrosive environments. In this case, the anodizing time is usually increased to increase the thickness of the oxide film, or the surface is hard oxidized.
3. The quality and alloy composition of industrial aluminum profiles are not up to standard, or there are too many impurities, which will greatly affect the service life of industrial aluminum profiles. Especially iron, if the industrial aluminum profile contains a certain amount of iron, its corrosion resistance will be greatly reduced. In some factories, the surface of aluminum profiles reconstructed from waste aluminum is black and dark, that is, the iron content exceeds the standard.
