Alloy Identification
At AAA Air Support, we supply and distribute a wide range of aerospace-grade aluminum alloys to meet the demanding requirements of the aviation and aerospace industries. Below you’ll find quick-reference aluminum factoids and material data for the most common aircraft-grade aluminum alloys used in manufacturing, maintenance, and repair.
Whether you need material for aircraft skins, structural components, or precision-machined parts, AAA Air Support stocks and processes high-quality aluminum plate, sheet, bar, and extrusion — all certified to aerospace material specifications (AMS) and Boeing (BAC) standards.

2024-T3 Aluminum
2024-T3 is the universal aerospace alloy known for its excellent fatigue resistance and high strength-to-weight ratio. Often used in aircraft skins, cowls, bulkheads, and wing structures, this alloy is also a top choice for aircraft restoration projects due to its shiny Alclad finish.
Common Applications:
- Aircraft skins and structural panels
- Cowls and fuselage sections
- Aircraft restoration and repair
- Alclad for corrosion protection
Technical Data:
- Ultimate Tensile Strength: 62,000 PSI
- Shear Strength: 40,000 PSI
- Weldability: Not recommended
- Excellent fatigue resistance
6061-T6 Aluminum
6061-T6 aluminum is highly versatile with excellent corrosion resistance, weldability, and finish quality. While slightly lower in strength than 2024 or 7075, its exceptional formability makes it ideal for both aircraft structural use and industrial fabrication.
Common Applications:
- Aircraft landing mats and frames
- Structural components and brackets
- Aerospace tooling
- High-end bicycle frames
Technical Data:
- Ultimate Tensile Strength: 45,000 PSI
- Shear Strength: 30,000 PSI
- Excellent weldability and machinability
- Comparable in strength to mild steel but much lighter
7075 Aluminum
7075 is one of the strongest aluminum alloys available, commonly used in aircraft structures that demand high strength and toughness. Containing zinc, magnesium, and copper, 7075-T6 is well known for its high strength-to-weight ratio and excellent anodizing properties.
Common Applications:
- Aircraft structural components
- Military-grade applications
- High-performance equipment
- Aerospace tooling
Technical Data:
- Ultimate Tensile Strength:
- 33,000 PSI (-O)
- 82,000 PSI (-T6)
- Shear Strength:
- 22,000 PSI (-O)
- 49,000 PSI (-T6)
- Machinability: Excellent
- Weldability: Poor (due to copper content)
5052-H32 Aluminum
5052-H32 is a non-heat-treatable alloy with high fatigue strength and exceptional corrosion resistance. Although not structural, it’s widely used in marine and fuel system applications due to its resistance to saltwater and chemicals.
Common Applications:
- Aircraft fuel tanks
- Marine components
- Sheet metal fabrication
- Storage tanks and enclosures
Technical Data:
- Non-heat treatable
- High corrosion resistance
- Excellent workability and formability
3003-H14 Aluminum
3003-H14 is one of the most widely used aluminum alloys due to its superior workability and moderate strength. It contains manganese for additional hardness and is ideal for cowling, baffles, and non-structural aircraft components.
Common Applications:
- Cowl and baffle plating
- Formed sheet metal parts
- General-purpose fabrication
- Decorative applications
Technical Data:
- Ultimate Tensile Strength: 21,000 PSI
- Shear Strength: 14,000 PSI
- Not heat treatable
- Easily deep drawn, spun, brazed, or welded
