2024 aluminium alloy: understanding its properties and uses

When considering different alloys for use in extrusion projects, it is important to understand the properties of each alloy and the way in which they compare with alternatives. 2024 aluminium alloy is an alloy that is frequently used in the aerospace industry. It is a high strength alloy for projects requiring high strength to weight ratios and fatigue resistance. As such, it is found primarily in wing and fuselage structures that are often subjected to tension. This alloy is usually extruded, but can also be found in sheet form.

Below we take a look at some of the general characteristics of 2024 aluminium alloy. This alloy has high strength, but relatively poor corrosion resistance and weldability compared to other grades of aluminium alloys, with good extrusion processability. As a 2000 series alloy, 2024 aluminium is often heat treated to improve its strength. common tempering options for 2024 aluminium alloys include T3, T4 / T351 and T851.

Now, you may be wondering about the composition of 2024 alloys. Let's take a look at the chemical composition of 2024 aluminium alloy. Like other 2000 series alloys, 2024 is primarily alloyed with copper. It also contains manganese and magnesium, and may sometimes contain smaller amounts of silicon, iron, chromium, zinc and/or titanium.
