Corrosion Resistance AA2014 Aluminum Plate For Aircraft Wing Spars
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.
Key Advantages
♦ High Strength: A high-strength Al-Cu-Mg alloy, achieving >450 MPa tensile strength (in T6 temper),
ideal for load-bearing structures.
♦ Lightweight: Density (~2.8 g/cm³) reduces aircraft weight vs. steel.
♦ Heat Resistance: Retains strength at elevated temperatures (e.g., supersonic aircraft).
♦ Machinability: Suitable for forging/extrusion into complex spar geometries.
♦ Fatigue Resistance: Good cyclic load performance for long service life.
Typical Thicknesses
Plates: 10–50 mm (primary load-bearing spars).
Thin Sheets: 2–10 mm (secondary structures).
Common Tempers
T6: Solution heat-treated + artificially aged. Maximizes strength (tensile: ≥450 MPa).
T4: Solution-treated + naturally aged. Balanced strength/formability.
O: Annealed (softened) for cold forming, requires post-forming heat treatment.
