![]() The result is a compound that forms a non-reactive oxide layer on the surface to protect the material underneath from further corrosion. It will react with water and bond with oxygen in the environment. For example, while aluminum is a passive material, it’s a reactive metal by nature. The degree and severity of aluminum corrosion have to be under the right conditions and stretch over weeks, months, or years. ![]() In extreme cases, rust (iron oxide) can cause structural damage like stress fractures and complete material failure. Metal corrosion of any kind can significantly impact the functionality of a workpiece. Corrosion refers to degeneration caused by environmental elements that happen naturally as nature attempts to return metals to their original state. Aluminum Corrosion: Does Aluminum Rust?Īluminum doesn’t rust but is susceptible to corroding, which is the wearing away of metal. Reach out to Minnesota Industrial Coatings for assistance with any aluminum corrosion issues. This article answers the question, ‘Does aluminum rust?’ It also discusses different types of corrosion. While this is a testament to aluminum’s recyclability and longevity, it’s susceptible to corrosion from acids, including alkalis, such as potassium hydroxide and sodium. Aluminum holds its value down the supply chain because, according to the Aluminum Association, approximately 75% of all aluminum produced is still in good use to date since the aluminum corrosion resistance is excellent. ![]() This makes it the most extensively used non-ferrous metal, with typical applications ranging from marine and aerospace to construction and cookware. Aluminum, a lightweight silvery-white metal, is one of the earth’s crust’s most plentiful metallic elements. ![]()
