6061 alloy aluminum plate is a commonly used machined aluminum plate. Customers may no longer undergo surface treatment after purchasing 6061 alloy aluminum plate. However, will corrosion occur when 6061 aluminum plate is stored for a long time? Below, the 6061 aluminum plate manufacturer will analyze it for everyone.
 

6061 alloy aluminum plate does not contain iron or steel elements, so it will not rust, but it is very prone to corrosion when exposed to air. The process of corrosion of 6061 alloy aluminum plate is called oxidation. The oxidized alumina layer is thin. When the aluminum plate is oxidized, a hard oxide film will be formed on the surface, which will protect the aluminum plate from further oxidation. The corrosion of 6061 aluminum plate is actually due to oxidation, and unless the surface aluminum oxide is removed, 6061 aluminum plate will not undergo further oxidation. Unlike rust that contains blocky, red appearance, 6061 aluminum oxide film is not easy to fall off the metal surface. The oxidation rate of 6061 alloy aluminum plate depends on the type of aluminum, surface treatment, and natural environment around the aluminum. 6061 alloy aluminum plate is not prone to corrosion in the air, and forms an oxide film on the surface to maintain 6061 aluminum plate.
