Compare all 12 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Softest condition for deep forming, bending or machining of blanks before solution treatment. | 95 | 185 | 18 | 45 HB | 50 % IACS |
Slightly strain hardened | As-supplied extruded/annealed stock with incidental work hardening from straightening; use where near-O softness is acceptable. | 110 | 200 | 16 | 50 HB | 49 % IACS |
solution treated, stress-relieved by stretching (extrusions, without/with minor straightening), naturally aged | Naturally aged extruded shapes with controlled residual stress; T3511 permits minor straightening after stretching. | 270 | 415 | 14 | 103 HB | 34 % IACS |
extrusions solution treated, stretch stress-relieved (no / minor straightening), naturally aged | Naturally aged, low-stress extruded profiles for parts machined all over then artificially aged. | 270 | 415 | 14 | 103 HB | 34 % IACS |
T3, stress relieved by stretching | Low-residual-stress plate/bar for stability during heavy machining before final ageing to T6 conditions. | 275 | 425 | 16 | 105 HB | 34 % IACS |
T4, stress relieved by stretching | T4 plate/bar with stretch stress relief — the stock of choice for machining large fittings that will later be aged. | 280 | 425 | 16 | 105 HB | 34 % IACS |
Solution heat treated and naturally aged | Best combination of strength and ductility for forming/riveting; parts can be aged to T6 afterwards. | 290 | 427 | 20 | 105 HB | 34 % IACS |
Solution heat treated, cold worked and naturally aged | Sheet/strip condition combining naturally aged strength with residual cold work; good for formed and riveted skins. | 295 | 440 | 15 | 105 HB | 34 % IACS |
Solution heat treated and artificially aged | Peak-strength condition for forgings, bar and sheet where maximum static strength and hardness are required. | 414 | 483 | 11 | 135 HB | 40 % IACS |
T651Default T6, stress relieved by stretching | Default stocked plate/bar temper: peak strength with low residual stress for distortion-free precision machining. | 415 | 470 | 9 | 135 HB | 40 % IACS |
extrusions solution treated, stretch stress-relieved (no / minor straightening), artificially aged | Peak-strength extruded bar and profiles with controlled residual stress for machined structural fittings. | 415 | 470 | 8 | 135 HB | 40 % IACS |
T6, stress relieved by compression | Hand/die forging temper where stress relief is done by cold compression instead of stretching. | 415 | 470 | 8 | 135 HB | 40 % IACS |
What is 2014A?
2014A is the British/European variant of 2014 (former BS H15), an Al-Cu-Si-Mg alloy (AlCu4SiMg(A)) with slightly adjusted composition limits and used interchangeably with 2014 in structural forgings. Engineers specify it for high heat-treated strength — 415 MPa yield, 470 MPa tensile, 9% elongation and 135 HB (80 HRB) in the default aged condition — supplied as forgings, extrusions, plate and bar in O, T3/T4 and T6 temper families. The limits are poor arc weldability, low cold formability, moderate corrosion resistance and a maximum service temperature near 150 °C. Use 7075 where higher strength is needed and 6061 where welding or corrosion resistance dominate. 2014A 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). 2014A 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 2014A
Is 2014A easy to machine?
Machines very well in T4/T6 with sharp carbide tools, high speed and flood coolant, giving short chips; annealed stock is gummy and should be avoided for fine finishes.
Can 2014A be welded?
Poor for MIG/TIG welding — hot-cracking prone; join by riveting, bolting, friction-stir or resistance spot welding, and use 4043/2319 filler only for non-critical repairs with post-weld heat treatment.
Can 2014A be formed, bent or molded?
Form in O or freshly quenched T4 (within a few hours of quench, or hold at −18 °C); T6 has limited bend ductility and requires generous bend radii; excellent hot forgeability at 400–460 °C.

What surface finishes work on 2014A?
Chromic or sulfuric anodizing gives a dark, non-decorative film — use conversion coating plus epoxy primer, Alclad, or hard anodize for wear; avoid direct contact with steel/stainless without insulation to prevent galvanic attack.

2014A — frequently asked
What is 2014A used for?
2014A is typically used for aircraft forgings, structural extrusions and wheels. In short: high-strength 2000-series forging alloy; 2014 to European limits; strong but not weldable.
What is the yield strength of 2014A?
2014A has a typical yield strength of 415 MPa (60.2 ksi) and a tensile strength of 470 MPa (68.2 ksi) — stronger than 89% of aluminum grades. Strength varies by condition: see the 12 listed tempers.
Is 2014A easy to machine?
Yes — machinability is rated very good (80/100, better than 92% of aluminum grades). Machines very well in T4/T6 with sharp carbide tools, high speed and flood coolant, giving short chips; annealed stock is gummy and should be avoided for fine finishes.
Can 2014A be welded?
Not readily — weldability is rated poor (25/100). Poor for MIG/TIG welding — hot-cracking prone; join by riveting, bolting, friction-stir or resistance spot welding, and use 4043/2319 filler only for non-critical repairs with post-weld heat treatment.

What is the maximum service temperature of 2014A?
2014A is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 2014A-T651 and 2014A-O?
T651 is the default condition — default stocked plate/bar temper: peak strength with low residual stress for distortion-free precision machining. O: softest condition for deep forming, bending or machining of blanks before solution treatment. Yield strength is 415 MPa in T651 versus 95 MPa in O.
How much does 2014A cost?
