Aluminum Alloy 2024 Data Sheet

ALUMINUM ALLOY 2024 GENERAL DESCRIPTION :

What is Alloy 2024?

2024 aluminum alloy offers high strength, good heat treatment response, and fair machinability. Its main advantages are a high strength-to-weight ratio and good fatigue resistance. It’s widely used in aerospace due to these properties but has poor corrosion resistance unless coated.

Product Capacities of Alloy 2024

Typical Uses

2024 aluminum alloy is widely used in the aerospace industry and usually in sheet/plate form (called aircraft aluminum sheet/plate), particularly for aircraft structures such as fuselage and wing components.

This alloy is known for its high strength and excellent fatigue resistance, making it ideal for applications that endure significant stress and require a high strength-to-weight ratio.
Despite its high strength, 2024 aluminum has relatively poor corrosion resistance, often requiring cladding with aluminum (called Alclad) or coating to enhance its durability in environmental exposures.

FAQs

Is 2024 Aluminum Stronger than 6061?

Yes, 2024 aluminum is generally stronger than 6061 aluminum. 2024 aluminum has a higher yield strength compared to 6061 aluminum, making it more suitable for applications where high strength is critical, such as in aircraft structures. However, 6061 aluminum offers better corrosion resistance and is easier to weld and machine. If you want to learn more about the difference between these two alloys, read our blog: 2024 aluminum vs 6061 aluminum.

Is 2024 Better than 7075 for Fatigue Strength?

No, 7075 aluminum typically offers better fatigue strength compared to 2024 aluminum. While 2024 aluminum has good fatigue resistance, 7075 aluminum is a preferred choice in high-stress applications like aerospace and military uses.
