Compare all 6 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Stress relieved | Use to remove build residual stress before plate removal when full solution treatment is not wanted; strength drops, ductility rises. | 200 | 300 | 12 | 85 HB | 42 % IACS |
As built (as printed) | Pick for quick prototypes or when no furnace cycle is available; retains fine as-solidified structure with moderate strength. | 300 | 400 | 7 | 110 HB | 26 % IACS |
Solution heat treated and naturally aged | Best balance of strength and ductility/damage tolerance for structural AM parts, mirroring wrought 2024-T3/T4 behaviour. | 330 | 470 | 11 | 120 HB | 30 % IACS |
Solution heat treated and overaged (stabilized) | Choose for improved dimensional stability, intergranular/exfoliation corrosion resistance and elevated-temperature stability at some strength cost. | 370 | 440 | 8 | 125 HB | 37 % IACS |
T6Default Solution heat treated and artificially aged | Default choice when maximum yield strength and hardness are needed and moderate ductility is acceptable. | 430 | 500 | 6 | 140 HB | 32 % IACS |
hot isostatic pressed then solution treated and artificially aged | Specify for fatigue-critical or flight-hardware parts where residual gas porosity must be closed before ageing. | 430 | 505 | 8 | 140 HB | 32 % IACS |

What is A2024-RAM2?
A2024-RAM2 is a nano-functionalized version of the classic 2024 Al-Cu-Mg wrought chemistry, seeded with ceramic nucleants so it solidifies crack-free in LPBF. Engineers use it to print aerospace-grade parts at wrought-2024-like strength: 430 MPa yield, 500 MPa tensile, 6 % elongation, 140 HB, 120 W/m·K and 32 % IACS in the default condition, with AB, SR, T4, T6, T7, HIP+T6 and powder listings on file. Corrosion resistance is low (score 33) and service tops out at 150 °C, so coatings are mandatory in chlorides. It is not fusion weldable; A6061-RAM2 is the alternative when weldability and conductivity matter more than strength. A2024-RAM2 has a density of 2.78 g/cm³ (0.1 lb/in³), heavier than 74% of aluminum grades. It melts at 502°C (936 °F). A2024-RAM2 has a yield strength of 430 MPa (62.4 ksi) and a tensile strength of 500 MPa (72.5 ksi) — stronger than 90% of aluminum grades. Elongation at break is 6% and the elastic modulus is 78 GPa (11.3 Msi).

Working with A2024-RAM2
Is A2024-RAM2 easy to machine?
Machines like wrought 2024 but the hard ceramic dispersoids are abrasive — use polycrystalline diamond or coated carbide, sharp positive rake, high speed and flood coolant.
Can A2024-RAM2 be welded?
Not recommended for fusion welding (Al-Cu-Mg hot-cracking sensitivity); join by fasteners, adhesive or friction stir where qualified.
Can A2024-RAM2 be formed, bent or molded?
Produced net shape by LPBF at ~30–60 µm layers with preheated plate; the RAM nucleant suppresses solidification cracking, so no cold forming step is involved.

A2024-RAM2 — frequently asked
What is A2024-RAM2 used for?
A2024-RAM2 is typically used for aerospace structural parts, high-strength brackets and replacement of wrought 2024 components. In short: printable 2024 chemistry; high strength, low corrosion resistance; not fusion weldable.
What is the yield strength of A2024-RAM2?
A2024-RAM2 has a typical yield strength of 430 MPa (62.4 ksi) and a tensile strength of 500 MPa (72.5 ksi) — stronger than 90% of aluminum grades. Strength varies by condition: see the 6 listed tempers.
Is A2024-RAM2 easy to machine?
Reasonably — machinability is rated good (55/100, worse than 59% of aluminum grades). Machines like wrought 2024 but the hard ceramic dispersoids are abrasive — use polycrystalline diamond or coated carbide, sharp positive rake, high speed and flood coolant.
Can A2024-RAM2 be welded?
Not readily — weldability is rated poor (25/100). Not recommended for fusion welding (Al-Cu-Mg hot-cracking sensitivity); join by fasteners, adhesive or friction stir where qualified.
What surface finishes work on A2024-RAM2?
Support removal, blasting and machining of critical faces; protect with hard anodize, chromate-free conversion coat or primer — bare Cu-bearing surfaces pit readily in chlorides.
Can A2024-RAM2 be formed, bent or molded?

What is the maximum service temperature of A2024-RAM2?
A2024-RAM2 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 A2024-RAM2-T6 and A2024-RAM2-SR?
T6 is the default condition — default choice when maximum yield strength and hardness are needed and moderate ductility is acceptable. SR: use to remove build residual stress before plate removal when full solution treatment is not wanted; strength drops, ductility rises. Yield strength is 430 MPa in T6 versus 200 MPa in SR.
