Aluminium tube 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.
Modern mills are able to produce aluminium tube to many different tempers allowing for maximum flexibility in the design process. A variety of production techniques can be used to produce different properties including direct/indirect extrusion, porthole extrusion and various drawing techniques. Stocks are held in a range of both metric and imperial sizes.

Available Products |
1200
BS |
L54, L116 |
A low strength alloy (though slightly higher than 1050A) with excellent resistance to atmospheric and chemical corrosion resistance. Easily worked and welded finding applications where ductility if important. |
2014A
BS |
L105, L63 |
A high strength alloy containing 4 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
AMS
FED |
4088
WW-T-700/3 |
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. |
3003
AMS
FED |
4065
WW-T-700/2
QQ-A-200/1 |
A non-heat treatable medium strength alloy with better mechanical properties than 1000 series alloys particularly at elevated temperatures. Good formability and weldability. Excellent resistance to atmospheric and chemical corrosion. |
5251
BS |
L56 |
A medium strength aluminium alloy with high corrosion resistance. This alloy is weldable and finds many applications in marine environments. The quarter hard temper allows this alloy to undergo limited bending and forming operations. |
5052
AMS
FED |
4070, 4071
WW-T-700/4 |
A medium strength alloy usually specified only within the USA. Higher strength than 5251 & 3003 alloys and slightly better corrosion resistance in marine environment to 1200 alloy. Easily formed and welded. |
6061
BS
AMS
FED |
L117, L118
4080, 4083
WW-T-700/6 |
A medium strength alloy with good corrosion resistance and good workability. In the annealed condition it can be easily welded and formed. More popular in the USA this alloy is often replaced by 6082 in Europe. |
6082
BS |
L114 |
A popular medium strength alloy with good corrosion resistance and good workability. In the annealed condition it can be easily welded and formed. Good anodising properties. Designed as a general purpose alloy it is suitable for many applications. |
7075
FED |
WW-T-700/7
QQ-A-200/11 |
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, often used for highly stressed parts. |
