Compare all 7 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Softest condition for deep forming, heavy bending or straightening before solution treatment. | 95 | 185 | 18 | 45 HB | 50 % IACS |
Solution heat treated and naturally aged | Choose when moderate strength with better ductility and forming/riveting capability is needed before final aging. | 290 | 425 | 18 | 105 HB | 34 % IACS |
T4, stress relieved by stretching | Plate/bar version of T4 with low residual stress — for parts that will be machined then artificially aged. | 290 | 425 | 16 | 105 HB | 34 % IACS |
T6, stress relieved by compression | Hand/die forging condition where stretching is impractical; low residual stress for heavily machined forgings. | 400 | 460 | 8 | 130 HB | 40 % IACS |
Solution heat treated and artificially aged | Peak-strength condition for forgings, extrusions and machined fittings where residual stress is not critical. | 414 | 483 | 13 | 135 HB | 40 % IACS |
T6, stress relieved by stretching | Standard aerospace plate/bar condition — full T6 strength with minimal residual stress so machined parts stay flat. | 415 | 470 | 9 | 135 HB | 40 % IACS |

What is 2214?
2214 is the high-purity, low-iron registered variant of 2014, with Fe held below 0.30 % to improve toughness and fatigue performance, in the heat-treatable Al-Cu-Si-Mg system. It is supplied mainly in T6/T651 as thick plate, forgings and extrusions for aircraft structural fittings, machined components and highly loaded tooling, reaching strength close to medium-carbon steel at about one third the density. Corrosion resistance is poor and needs cladding, anodizing or coating, fusion welding is hot-crack prone, and formability is moderate; standard 2014 is the more available equivalent. 2214 has a density of 2.8 g/cm³ (0.101 lb/in³), heavier than 81% of aluminum grades. It melts at 507°C (945 °F). 2214 has a yield strength of 415 MPa (60.2 ksi) and a tensile strength of 470 MPa (68.2 ksi) — stronger than 89% of aluminum grades. Elongation at break is 9% and the elastic modulus is 73 GPa (10.6 Msi).

Working with 2214
Is 2214 easy to machine?
Excellent chip control in T6/T651 — use polished-flute carbide, high speeds with flood or MQL; avoid re-introducing residual stress in thin machined webs.
Can 2214 be welded?
Not recommended for fusion welding (hot cracking with Cu-rich melt); join by rivets, bolts, adhesive or friction-stir; if arc welded, use 4145/4043 filler and re-heat-treat.
Can 2214 be formed, bent or molded?
Form in O or fresh T4 (within a few hours of quench, or hold sub-zero); T6/T651 has limited bend ductility and springback is high.

What surface finishes work on 2214?
Chromic-acid anodize, chemical conversion coat or alclad plus epoxy primer for corrosion protection; sulfuric anodize gives dark, non-uniform color due to CuAl2 phases.
