- Source: 2014 aluminium alloy
2014 aluminium alloy (aluminum) is an aluminium-based alloy often used in the aerospace industry.
It is easily machined in certain tempers, and among the strongest available aluminium alloys, as well as having high hardness. However, it is difficult to weld, as it is subject to cracking.
2014 is the second most popular of the 2000-series aluminium alloys, after 2024 aluminium alloy. It is commonly extruded and forged. The corrosion resistance of this alloy is particularly poor. To combat this, it is often clad with pure aluminium. If unclad 2014 aluminium is to be exposed to the elements, it should be painted as a corrosion protection measure.
Prior to the adoption of The Aluminum Association alloy designations in 1954, 2014 was known by the industry conventional designation "14S".
Chemical composition
The alloy composition of 2014 is:
Aluminium: Remainder
Chromium: 0.1% max

Titanium + Zinc: 0.2% max
Zinc: 0.25% max
2014A Aluminium Alloy
2014A is an alloy of aluminium that is very similar (but not entirely identical) to 2014. Because of the naming similarity, the two can be confused. The alloy composition of 2014A is:
Aluminium: Remainder
Chromium: 0.1% max
Copper: 3.9% - 5%
Iron: 0.5% max (versus 0.7 for 2014)
Magnesium: 0.2% - 0.8%
Manganese: 0.4 - 1.2%
Remainder: Each 0.05% max
Remainder: Total 0.15% max
Silicon: 0.5% - 0.9% (versus 0.5-1.2 for 2014)
Titanium: 0.15% max
Titanium + Zinc: 0.2% max
Zinc: 0.25% max
