Aerospace Aluminium Bar - International Specifications

Aluminium bar 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. Stocks are carried in a range of sizes selected to best match the requirements of current aircraft build programmes.

Available Products

2014A

A high strength alloy containing 3.9 to 5% copper. High mechanical properties with good machinability. Finished components often need a protective coating to avoid corrosion. Cold formability can be limited when used fully heat treated, as can weldability.

2024

A heat treatable alloy with both high strength and excellent fatigue resistance. Workability is good and it can easily be machined to a high finish. Weldability is generally poor although it can be flash spot or seam welded if necessary. Often used in applications where a high strength/weight ratio is required.

4342

 

7075

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. Reasonable machinability and it finds many applications in the aerospace sector where it is often used for highly stressed parts.
