2xxx Series 2014 Aluminum Alloy Sheet For Aerospace Industry
2014 alloy is primarily used in aerospace/military applications
where high strength is critical.
For commercial uses, modified 2XXX/7XXX alloys are often preferred
due to better corrosion
resistance.
Properties of 2014 Aluminum Alloy
Composition:
Primarily composed of copper (3.9–5.0%), magnesium (0.2–0.8%), and
manganese (0.4–1.2%).
Strengthened by precipitation hardening (θ' and S phases).
Mechanical Properties:
Tensile strength: ≥425 MPa (T6 temper)
Yield strength: ≥370 MPa
Elongation: 3–10% (varies with temper)
Corrosion Resistance:
Poor due to high copper content; requires alclad (pure aluminum
cladding) or coatings for skin
applications.
Workability:
Good hot workability but challenging for cold working (annealing
may be needed).
Advantages for Aircraft Skin
♦ High Strength-to-Weight Ratio:
Comparable to steel, reducing structural weight and improving fuel
efficiency.
♦ Fatigue Resistance:
Suitable for cyclic aerodynamic loads during flight.
♦ Formability:
Compatible with riveting, welding (with specialized techniques),
and shaping (e.g., curved
skin panels).
♦ Cost-Effectiveness:
More economical than advanced alloys like 2024 or 7075, ideal for
non-critical structures.
