Aluminum 2014 is a main kind of aircraft aluminum sheets while Al6061 is also used for some parts of the aircraft. What are their differences?
2014 aluminum sheet a Al-Cu-Mg-Si high-strength forged aluminum alloy, which can be strengthened by heat treatment. The chemical composition of the alloy is similar to that of 2A14 aluminum alloy, and it has high strength and good hot workability.
Due to the high copper content of the alloy, its corrosion resistance is poor, and it is prone to intergranular corrosion and stress corrosion. Its weldability and cutting performance are both good. It can also produce 2014 clad aluminum to improve its corrosion resistance.
Aluminum 2014 is used to manufacture parts that require high strength, high hardness and high load, such as truck frames and suspension assemblies, fuel tanks and structural parts of rocket boosters, etc.
2014 aluminum alloy has good plasticity in the hot state, and can manufacture daggers and die forgings with complex shapes. The formability in cold state is poor, usually the forging temperature range is 440--320℃.

The main alloying elements of 6061 aluminum sheet are magnesium and silicon, sometimes a small amount of copper and zinc are added to improve the strength of the alloy. There is also a small amount of copper in the conductive material, which can offset the effect of titanium and iron on conductivity. This alloy has moderate strength, good corrosion resistance, weldability, and good overall oxidation.
Through a special pre-stretching process, 6061 aluminum plate has good processing performance, good corrosion resistance, high toughness, and is not easy to deform after processing. It is widely used in various industrial structural parts that require certain strength and high corrosion resistance, such as the manufacture of trucks, tower buildings, ships, trams, and railway vehicles.
