![]() On the other hand, iron and steel are ferrous metals that contain iron and are susceptible to rust formation in the presence of water and oxygen. Aluminum, being a non-ferrous metal, does not contain iron and is therefore not prone to rusting. In conclusion, the difference between aluminum and iron/steel in terms of rust formation lies in their composition. Property Aluminum Iron/Steel Composition Non-ferrous metal (no iron) Ferrous metal (contains iron) Tendency to rust Does not rust Prone to rusting Corrosion resistance Resistant to corrosion Susceptible to corrosion Weight Lightweight Heavy Appearance Maintains appearance over time Can become unsightly due to rust formation While aluminum can still be affected by other forms of corrosion, such as white rust or galvanic corrosion, it is much more resistant to corrosion than iron and steel. This means that it is not prone to rusting, as there is no iron present to react with water and oxygen. This reaction weakens the metal and can cause it to become unsightly over time.Īluminum, on the other hand, is a non-ferrous metal that does not contain iron. In the presence of these three elements, iron reacts with water and oxygen to form iron oxide, which is commonly known as rust. The ingredients that contribute to rust formation in iron and steel are iron, water, and oxygen. Сomparison table between Aluminum and Iron/Steel And the best part is, aluminum products stay looking good and performing well for years, even in harsh environments! It’s also widely used in the manufacture of consumer goods like electronics, appliances, and sporting goods. One of the things I love about aluminum is that it’s so versatile! It’s used in everything from cars and airplanes to packaging and construction. But, compared to iron and steel, aluminum is much more resistant to corrosion, and it’s also much lighter, making it a popular choice for many applications. It can still be affected by other forms of corrosion, like white rust or galvanic corrosion. Now, that’s not to say that aluminum is completely immune to corrosion. That means there’s no iron to react with water and oxygen and form rust. With aluminum, though, you don’t have to worry about that! Aluminum is a non-ferrous metal, which means it doesn’t contain iron. The result is a red-brown flaky substance that can weaken the metal and make it look unsightly. Rust is a form of corrosion that occurs when iron reacts with water and oxygen.
