ABOUT ALUMINUM 2024-T3
Aluminum 2024-T3 is a high-strength aluminum-copper alloy that has been the workhorse of aerospace structures since the 1930s. It offers an excellent strength-to-weight ratio and good fatigue resistance, making it ideal for aircraft fuselage skins and wing structures. It is commonly clad with pure aluminum (Alclad) for corrosion protection.
