Aluminium has become a popular choice in modern construction because of its strength, durability, and versatility. However, one quality that marks this metal out from all the rest is that it does not rust.
But why is that?
At BB Fabrications, we’d like to take this opportunity to explore our favourite fabrication material and explain to you why it quite simply does not rust.
What Is Rust?
Rust results from a chemical reaction between iron, oxygen, and water. This reaction causes the metal to corrode and form a reddish-brownish layer of iron oxide. Then, over time, this layer further corrodes and weakens the metal. This results in a metal that is weak and prone to breaking.
Why Doesn’t Aluminium Rust?
Unlike iron and other metals, aluminium is what is known as a non-ferrous metal. This means that it does not contain iron. In turn, this means that there can be no layer of iron oxide when the metal oxidises after it comes into contact with water and oxygen.
Instead, this metal forms a protective layer when it oxidises that is only a few nanometres thick. Instead of corroding the metal, this oxide layer protects it. What’s more, this layer is actually self-repairing. If it’s damaged, it will use the oxygen and moisture in the air to form a brand-new oxide layer.
The Benefits Of Aluminium For Metal Fabrication
The fact that it does not rust makes it an excellent choice for metal fabrication. This is especially the case for projects such as sliding doors, patio doors, and windows. Here are some of the benefits of using this metal for these types of projects.
It is an incredibly durable metal, able to withstand harsh environmental conditions without rusting or corroding easily. This makes it an excellent choice for doors and windows; items that are regularly exposed to the elements.
Aluminium is very strong and can support heavy weight without bending or breaking. This is important for sliding doors and patio doors that need to withstand the weights like large glass panels.
Unlike iron or any other ferrous metal, which needs to be regularly painted or coated to prevent rust, aluminium doesn’t. Often, the most work that needs to go into maintaining anything made from this metal is a quick wipe down.
