Aluminium 1100 vs. 2024 – What’s the Difference

Aluminium 1100 vs. 2024

If you’re in the market for structural aluminum, you may have come across two common alloys: 1100 and 2024. These two alloys have slightly different properties and, therefore, can be used for various applications. In this blog post, we’ll be taking a look at the differences between aluminium 1100 and 2024 to help you determine which one is best suited for your project.

Difference Between Aluminium 1100 and 2024

First off, let’s take a look at what sets these two alloys apart from one another. Aluminium 1100 is commercially pure aluminum with excellent formability and corrosion resistance. On the other hand, Aluminium 2024 is an aerospace-grade alloy that provides superior strength but has lower formability due to its higher alloy content.

aluminum 1100 has good electrical conductivity and thermal conductivity, making it ideal for electrical components such as wiring harnesses or heat sinks. It also has excellent weldability and can be easily machined into complex shapes. aluminum 2024 offers similar machinability but with higher strength due to its alloy content. Additionally, it offers greater fatigue strength than 1100, making it ideal for aircraft components or other parts that require high levels of durability.

In terms of cost, Aluminium 1100 is generally cheaper than aluminum 2024 due to its lower amount of alloying elements. However, due to its higher strength properties, Aluminium 2024 may be more cost-effective over time since it requires less maintenance or replacement than softer alloys like 1100.


When choosing between aluminium1100 and 2024 for your project, it really depends on what type of application you need them for. For general-purpose applications that require good formability, corrosion resistance and low cost per pound without sacrificing too much strength, aluminium1100 is an excellent choice. However, if you are looking for greater strength in an aerospace-grade alloy without breaking the bank, then consider using aluminum 2024 instead. Both materials offer their own set of advantages, so make sure to carefully consider your needs before deciding which one best fits your project requirements!
