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.

Key Properties

Chemical Composition

Al-Cu-Mg-Si series alloy containing:

Cu (3.9-5.0%)

Mg (0.2-0.8%)

Si (0.5-1.2%)

Mechanical Properties

Tensile strength:

T6 temper: ≥480 MPa

T4 temper: ≥425 MPa

Elongation: 8-10% (T6)

Hardness: Up to 135 HB (T6)

Corrosion Resistance: Poor - requires surface protection

Heat Treatment: Responds well to T4/T6 tempers

Common Tempers
