![]() ![]() However, aluminum is vulnerable to certain types of corrosion. What Is The Best Way To Protect Aluminum From Corroding?Īluminum is a relatively strong and lightweight material that resists corrosion. This results in rust’s characteristic reddish-brown color and often the distinctive smell associated with it. When this happens, a new substance called an oxide is created, which often has a different color from the original substance. The oxidizing agent, in this case, is typically water (but it can also be oxygen). The Causesīoth types of degradation happen because of oxidation-the process by which a substance loses electrons when exposed to an oxidizing agent. In other words, all rust is corrosion, but all corrosion is not rust. The DifferencesĬorrosion is a process where a material degrades when exposed to air or water, but rusting is only corrosion that occurs specifically to iron or steel when they react with oxygen in the presence of water or moisture. In fact, they are very different processes with different causes and outcomes. However, rusting and corroding are not the same things. Rusting and corroding are two methods of degradation that affect the same elements: iron and steel. What Is The Difference Between Rusting And Corroding? However, this type of corrosion would not cause structural damage to the plane itself because it would not be able to penetrate below the surface oxide layer. ![]() For example, if salty water or acidic rainwater gets on an aluminum plane, it could cause corrosion on the plane’s surface. This unique property of aluminum makes it a popular choice for many applications, including aviation.Īluminum alloys may contain other elements such as copper and magnesium that can react with oxygen, so some types of aluminum may corrode under certain conditions. When exposed to oxygen, aluminum forms a thin oxide layer, but this layer prevents further corrosion by blocking oxygen from reacting with the metal underneath. When most metals react with oxygen, they form oxides, resulting in corrosion. The reason why aluminum does not rust is how it reacts with oxygen. Even though aluminum is a reactive metal and rust is an oxide, the answer to does aluminum rust is no. However, this quest for a simple solution is precisely what makes finding one so tricky. After all, in such a technological age where we can clone sheep (um…for the record, that wasn’t actually possible), it seems unthinkable that a simple solution couldn’t be found. The question of does aluminum rust has confounded scientists, auto mechanics, and dedicated researchers for centuries. ![]()
