Does Aluminum Rust or Corrode? Aluminium Corrosion …

When aluminum is placed in water, this passivation film isolates the water from the internal metal aluminum, so aluminum will not rust in water. Does Aluminum Rust in Saltwater Aluminum can rust in saltwater because the saltwater contains a large amount of chloride ions (Cl-), which can destroy the oxide film on the aluminum surface, causing pitting and intergranular corrosion.
