Aerospace Aluminium Sheet - International Specifications

Aluminium sheet is produced to international aerospace specifications in a wide variety of alloys. Physical and mechanical properties vary a great deal depending on the alloy and the heat treatment employed, making correct product selection critical. Flatness is often another key consideration when selecting the right product for a specific application. Stocks are carried in a range of sizes selected to best match the requirements of current aircraft build programmes.

Available Products

1200

A low strength alloy (though slightly higher than 1050A) with excellent resistance to atmospheric and chemical corrosion resistance. Easily worked and welded.

BS L16, L17

2014A bare / clad

A high strength heat treatable alloy with good machinability but limited weldability. Natural corrosion resistance is poor therefore a protective coating (cladding) is often required to prevent corrosion.

BS

FED
L156/7/8/9 (bare)
L163/4/5/6/7 (clad)
QQ-A-250/3

2024 bare / clad

A high strength heat treatable alloy with excellent fatigue resistance. Workability is good and it can easily be machined to a high finish. Weldability is generally poor.

BS L109, L110 (clad)

2618A

A high strength alloy with fair corrosion resistance. Good retention of strength at 200oC and above. Often used in high temperature aerospace and motorsport applications.

3103

A low to medium strength aluminium alloy that combines very good resistance to corrosion with good weldability and formability.

BS L59, L60, L61

5052

A medium strength alloy with slightly higher strength than 5251. Very good corrosion resistance in marine and industrial environments. Very good weldability.

FED QQ-A-250/8

5251

A medium strength aluminium alloy with high corrosion resistance. This alloy is weldable and finds many applications in marine environments.

BS L80, L81

6061

A medium strength alloy with good corrosion resistance and good workability. In the annealed condition it can be easily welded and formed.

FED QQ-A-250/11

6082

A popular medium strength alloy with good corrosion resistance and good workability. In the annealed condition it can be easily welded and formed.

BS L113

7050

A high strength heat treatable alloy with excellent resistance to stress corrosion (better than 7075). Reasonable machinability but poor workability.

7075 bare / clad

A high strength heat treatable aluminium alloy with excellent hardness properties. In the annealed condition this alloy can be flash or spot welded and is easily formed. Often used for highly stressed parts.

FED
L88 (obs)
QQ-A-250/12, 250/24
QQ-A-250/13 (clad)

7475

Similar properties to 7075 but with closer controls on iron and silicon content to optimise strength and toughness.
