2xxx Series 2014 Aluminum Alloy Sheet High Strength For Aerospace Industry

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
