2024 Aluminum Shafts

High-strength aerospace aluminum with excellent fatigue resistance — common in aircraft structure and high-stress fittings.

At a glance

2024-T3 built its reputation in aircraft structure: high strength paired with the best fatigue behavior of the common aluminum alloys. For parts that live under vibration and repeated load cycles — linkages, fittings, actuation hardware — it is the traditional aerospace answer.

Like its 2000-series sibling 2011, corrosion resistance is a weak point (aircraft sheet is clad for a reason) and welding is off the table. Anodize or prime it for anything exposed.

When to choose 2024-T3

Fatigue life under cyclic load is the driving requirement.
Aerospace prints and legacy designs that specify 2024.
High-stress fittings and linkage components.

Consider instead

7075 — higher static strength.
6061 — better corrosion resistance and weldability.

Typical applications

Aircraft linkages and fittings
Actuation shafts under cyclic load
Vibration-exposed brackets and pins
Legacy aerospace replacement parts

Frequently Asked Questions

7075 has higher static strength; 2024 has the better fatigue reputation under repeated load cycles. Aerospace practice uses 2024 where vibration and cyclic stress dominate, 7075 where peak load does.

Yes, for any exposed service — its copper-rich chemistry corrodes readily. Anodizing or priming after machining handles it; aircraft skins solve the same problem with cladding.

No — like most 2000-series alloys it is effectively unweldable and loses its temper at the joint. Use mechanical fastening, or 6061 when welding is a hard requirement.
