2024 Aluminium Sheet

2024 Aluminium Sheet: Technical Details and Applications

2024 Aluminium Sheets are renowned for their high strength-to-weight ratio, making them perfect for applications where both performance and weight reduction are critical. This alloy offers excellent machinability and can be heat treated to enhance its strength. Commonly used in aerospace for aircraft structures and fuselage skins, 2024 aluminium is also used in military applications, including wing tension members and critical aircraft parts. The alloy’s moderate corrosion resistance requires protective coatings or anodizing for optimal performance in harsh environments.

In comparison to similar grades such as 7075 aluminium, which offers higher tensile strength, 2024 aluminium is favored for applications where fatigue resistance is prioritized. Price-wise, 2024 aluminium remains competitive, especially in comparison to 7050 or 7075 alloys, which are typically more expensive due to their higher strength and performance in extreme conditions.
