Why doesnt aluminium rust: Aluminium's immunity to rust arises from its remarkable capability to generate a protective oxide layer. When it comes into contact with oxygen in the atmosphere, aluminium undergoes a chemical transformation that results in the creation of a thin and firmly bonded aluminium oxide layer on its surface. This layer serves as a barrier, impeding further interaction with oxygen and moisture. Unlike iron's persistent rusting, the aluminium oxide layer effectively envelops the metal, shielding it from external elements. This natural protective shield guarantees aluminium's corrosion resistance, making it sturdy and well-suited for various applications in different environments.
