One of the benefits of using aluminium in windows is that the material is highly malleable. This means the material can be formed into different shapes without breaking. In terms of the use of aluminium in windows, it allows manufacturers to create custom window shapes, especially round or gothic arches. Aluminium also benefits from being lightweight as well as durable making it a stylish as well as practical material.
Choosing the right type of aluminium is imperative to ensure the material will bend into the correct shape. Like most metals, aluminium runs on a scale that takes into account several different factors. Some aluminium types will be more suited to different industries and processes. So if you’re keen to find out more, here’s the lowdown on what type of aluminium is easiest to bend.
Aluminium Types: An Overview
Every type of aluminium is unique and runs on a scale that factors in the following properties: grade, alloying elements, strengthening process, strength, welding, corrosion resistance, and formability. The main aluminium grade runs from type 1xxx to 8xxx.
As is common with any alloyed material, with every varying factor means a plus in one category and a trade off in another. This is similar to how 24ct gold is the purest form, however, it’s softness means it is unsuitable for jewellery. The same ethos applies with aluminium, in that some factors make it ideal for bending, but not for use in certain industries because of another property such as it’s corrosiveness. Or, how difficult it is to weld with for example.
Aluminium And Bending
The most popular aluminium types for bending fall between the 3xxx and the 6xxx varieties. The reason for this is because the other key properties such as strength, welding and corrosion resistance are the most suitable within this range. That being said, aluminium that is 4xxx or 6xxx has slightly less corrosion resistance. Though, it is still preferred compared with 7xxx which has a high corrosion resistance because this type of aluminium is not formable, meaning it does not bend into shape easily.
Architectural Powder Coating
Naturally, manufacturers and customers want the best of both worlds. This equates to an aluminium type that bends easily so it can be shaped to fit the customer’s needs but also isn’t corrosive. Though, one such solution is the use of architectural powder coating. This involves treating the aluminium with a special product that consists of free-flowing dry powder. The treatment is cured under heat, and once it sets will form a hard finish that is tougher than conventional paint.
As a result, architectural powder coating greatly boosts the longevity of aluminium. That’s because a physical layer has been applied protecting the aluminium from exposure to the elements. It’s also highly recommended for aluminium near coastal areas as saltwater can also act as a corrosive. Architectural powder coating is also a service we provide here at ABS. As well as protection against the elements, the process also allows you to customise the colour of your windows too.
Find Out More
When it comes to understanding what type of aluminium is easiest to bend, we hope the above information has been helpful. Ultimately, it’s about using an aluminium type that bends but also has other properties that make it suitable for the desired use. In the case of aluminium windows, this usually involves 3xxx types of aluminium such as 3003 or 5052.
