A2014
ISO N (non-ferrous)Aluminum alloy (heat-treatable Al-Cu-Si-Mg, 2000 series). Standard: Which JIS product standards list it (H 4000 sheet/plate, H 4040 bar, H 4140 forgings, etc.) is not confirmed in primary sources.
🌐International equivalents
“Close” means composition or properties are not exactly the same. Before substituting, check the values in each standard.

Differences between the equivalents (from the sources)
- EN EN AW-2014: There is a separate alloy EN AW-2014A (AlCu4SiMg(A)), which differs from 2014 in Si 0.50-0.9, Fe ≤0.50, Ni ≤0.10 and Zr+Ti ≤0.20 (AA Teal Sheets). The thyssenkrupp UK "2014" datasheet is actually 2014A, so it cannot be used as a source for 2014
- GB : Explanations equating 2A14 with 2014 are common, but this could not be confirmed in primary sources

✈Main aerospace uses (as stated in the sources)
- Aircraft structures (NASA: developed by Alcoa in 1928 as a high-strength alloy for heavy structures such as aircraft. Applications are heavy structures, aircraft structures, bridges, truck frames, rivets and structural fittings. Early on it was mainly used as forgings and extrusions)[26]
- Aircraft (in the Japan Aluminium Association alloy table, the applications listed for 2014, 2017 and 2024 are "aircraft, gears, hydraulic parts, hubs". Also used for forgings)[1]

🔧Machinability notes (as stated in the sources)
- AA comparative ratings (A-E): T3, T4, T451 = B; T6, T651, T6510, T6511 = B; O = D[18]
- In UACJ's table of forging alloys, 2014-T6 is rated "◎ (very good)" for machinability, ◎ for forgeability, and △ (somewhat poor) for corrosion resistance[12]
- NASA: general machining is easy in all tempers. Machinability is best in the hardest tempers, and softer tempers are somewhat gummy and harder to cut. For forgings with tight finished dimensions, machining in T4 is best; for open-die forgings with a lot of roughing, machine before heat treatment (F)[19]
