How To Protect Aluminium From Corrosion.Types of Metal That Are Corrosion Resistant or Don’t Rust.Take an everyday piece of furniture wood rots away from exposure to air moisture, steel corrodes with time due to its iron content, while aluminium ages imperceptibly. Aluminium is typically used in conjunction with other metals, such as copper, which act as a corrosion barrier. Under normal conditions, this layer helps stop further rusting. Surface aluminium oxide occurs on exposed aluminium alloys after prolonged air exposure. That appears too good to be true, but it is supported by research. It's not like iron or steel it won't corrode. If you've ever watched metal rust, you know it's a slow and steady process. Since the aluminium oxide coating prevents further contact between the metal and its surroundings, corrosion is effectively halted. Does aluminium ever rust?Īs a result of its reaction with oxygen in the air, a thin layer of aluminium oxide forms that prevents additional chemical reactions from damaging the metal. Can you explain what aluminium is? A chemical element having the symbol Al and atomic number 13, aluminium.
