Does Aluminium get Rust?

You might have heard that steel rusts, but what about aluminium? Can aluminum corrode, and if so, what is the process called? We’ll discuss these questions and more in this blog post.

Aluminum is a popular material used to build everything from cars to furniture. It’s light, malleable, and durable—all of which make it an ideal choice for many applications. But one common misconception is that aluminum can’t corrode as steel does. Is this true? The short answer is no. Aluminum can corrode just like any other metal; the process is simply known by a different name.

When iron corrodes, it forms iron oxide or “rust”, which gives the metal its characteristic reddish-brown colour. The same thing happens when aluminium corrodes; it forms a thin layer of oxide on its surface that helps protect it from further corrosion. This process is known as oxidation, and it’s completely natural and inevitable for all metals exposed to oxygen over time.

The good news is that compared to other metals, aluminum is relatively resistant to corrosion—especially when exposed to saltwater or acidic solutions. This means that even if your aluminum door frame begins to show signs of oxidation, you won’t have to worry about extensive damage or rusting taking place underneath the surface of the metal.


In conclusion, while all metals will eventually corrode, aluminum has much better resistance than most metals when exposed to corrosive substances such as saltwater or acid rain. However, if your aluminum items are beginning to show signs of oxidation (such as discolouration), you should take appropriate measures right away in order to prevent more serious damage from occurring down the road. With proper care and maintenance, your aluminium items should last you for years with minimal maintenance required!
