About aluminium 2014 – Tough enough for aerospace applications
Aluminium Alloy 2014 is a copper-based alloy with very high strength plus excellent machining characteristics at some tempers. This is the second most popular alloy in the 2000 series, the most popular of all being the metal’s 2024 alloy. 2014 is often extruded and forged and it’s one of the strongest aluminium alloys available, being unusually hard. It isn’t great for welding because it tends to crack. It comes with poor resistance to corrosion, which is why it’s often clad with pure aluminium. When unclad and used in a context where it’s exposed to the weather, it needs a coat of paint to reduce the risk of corrosion.

How is aluminium 2014 made?
Aluminium 2014 alloy is hardened using a precipitation heat treatment that takes the temperature to 502°C or 935°F. After that it’s quenched in water to create a T4 temper. Extra cold work post-hardening creates more tempers, namely T6511 and T6510 at 160°C or 320°F.
Why was aluminium 2014 invented?
Aluminium 2014 was created to meet an ongoing demand for an alloy that was super-strong and unusually hard, required for structural, aerospace and military applications.
What is aluminium 2014 used for?
Aluminium alloy 2014 is widely used in a variety of aerospace structural applications thanks to its very high strength. It’s also used in manufacturing military vehicles, weapons, lorry frames, bridges, and structural projects. Other applications include heat treatment and annealing.
What affects the price of aluminium 2014?
Supplies of aluminium 2014 affect the price, for example shipping delays like those caused by the grounding of the Ever Given, which blocked the Suez Canal for a week. The supply of aluminium can impact the cost of the alloy, as can trade wars and sanctions. Environmental issues brought about by the fight against climate change can also affect the supply of aluminium itself, as can worldwide issues like the covid pandemic.
