Do not edit your reply after posting it. 3) The answer is as follows: A dense oxide film forms on the aluminum surface, preventing the underlying metal from being further oxidized
Reply 1# eastchen: A layer of oxide film forms on the surface of aluminum, preventing further oxidation of aluminum and allowing it to remain stable
An oxide film forms on the surface of aluminum, preventing further oxidation and allowing aluminum to remain stable
1. There is an oxide layer on the surface； 2. Clean regularly (scrub).
An oxide film is formed on the surface to prevent the inner layer from oxidizing
A dense oxide protective film forms on the aluminum surface
Reply to 1# eastchen: The reason for its long-term use is that an oxide layer forms on the surface of aluminum, which prevents further oxidation of aluminum and allows it to remain stable
