Aluminium alloy in aircraft and aerospace industry

Aluminium alloy in aircraft and aerospace industry
In modern aircraft aluminium is used literally everywhere: in the fuselage, in the trims, in wing panes and in the rudder, in the tie down systems in the exhaust pipes, in the feeding blocks, in the refuelling hoses, in the door and floors, in the frames of pilot and passenger seats, in the fuel nozzles, in the hydraulic systems, in the cabin pillars, in ball bearings, in the instrumentation in the cockpit, in the engine turbines and in lots of other places.All types of vehicles, from bikes to spaceships, are made from aluminium. Transport also accounts for the largest share of aluminium consumption, that in some circles aluminium is known as the 'winged metal'.

Since then aluminium has become a key manufacturing material in aviation. The

The key aluminium alloys used in aviation are the 2ххх, 3ххх, 5ххх, 6ххх and 7ххх series. The 2xxx series is recommended for use in high temperature environments and in environments with an increased yield coefficient. The 7xxx alloys are used for lower temperature environments in parts exposed to increased loads and in parts that need to deliver high corrosion resistance under high voltage. 3xxx, 5xxx and 6xxx alloys are used in low load parts, as well as in hydraulic, lubrication and fuel systems.

The most widely used alloy is AA7075 aluminum . It consists of aluminium, zinc, magnesium and copper. It's the strongest of all aluminium alloys and comparable in that respect with steel, however it weighs only a third of what steel weighs.

Aluminium has proved indispensable not just in aviation but also in the aerospace industry where its combination of low weight and maximum strength is even more critical.

All modern spacecraft contain between 50% and 90% of aluminium alloys in their parts. Aluminium alloys are used in the body of Space Shuttle vehicles, they're found in the telescopic antenna of the Hubble space telescope; hydrogen tanks used in rockets are made from aluminium alloys, the tips of rockets use aluminium alloys, parts of launch vehicles and orbital stations, as well as the fastening units for solar panels – all these elements are made from aluminium alloys.
