2014 aluminium alloy

2014 aluminium alloy is an aluminium-based alloy often used in the aerospace industry.[1]

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.[2]

2014 is the second most popular of the 2000-series aluminum alloys, after 2024 aluminum 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 aluminum. If unclad 2014 aluminum is to be exposed to the elements, it should be painted as a corrosion protection measure.[3]

Prior to the adoption of The Aluminum Association alloy designations in 1954, 2014 was known by the industry conventional designation "14S".[4]

Chemical Composition

The alloy composition of 2014 is:[2]

2014A Aluminum Alloy

2014A is an alloy of aluminum 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:[1]

Properties

Typical material properties for 2014 aluminum alloy are:[5]
