Why Do Aluminium Sheets Not Corrode Easily

Aluminium on the other hand does not corrode easily because its surface is protected by a layer of aluminium oxide.

Why do aluminium sheets not corrode easily.

Its surface is protected by a natural layer of aluminium oxide. Why aluminium sheets do not corrode easily why does a copper vessel get covered with a green coating in rainy season science chemical reactions and equations. The short and simple answer is they are made of iron based metal and frequently exposed to rain and moisture hence they suffer from rust corrosion. Unlike rust which has a flaky reddish appearance aluminum oxidation cannot be easily chipped off the metal surface.

This can t continuously happen with aluminum because the oxygen can t get through the layer. Aluminium does not corrode easily because it reacts with atmospheric oxygen to form a thin layer of aluminium oxide over it. The process that causes copper carbonate to form is called oxidation the greenish tint on the copper is often referred to as patina when copper is first oxidized it does not immediately turn green. The aluminum corrosion process is actually halted by oxidation the metal won t continue to deteriorate unless the aluminum oxide is removed.

I hope my answer helps you. Aluminum unlike iron and steel does not rust or corrode in moist conditions. Even if it corrodes it reacts with oxygen to form a layer of aluminium oxide around it which protects it from further corrosion. This layer prevents further corrosin of aluminium.

Rust is an electrochemical process which occurs on metal surfaces that are exposed to the electrolytes. This green substance is called copper carbonate.
