Compare all 6 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Stress relieved | Use when distortion control and dimensional stability matter more than strength, e.g. before EDM cut-off or thin-wall heat exchangers. | 165 | 240 | 12 | 65 HB | 45 % IACS |
Solution heat treated and naturally aged | Choose when maximum ductility/toughness of a heat-treated print is wanted, or when parts will be straightened/formed before final aging. | 180 | 290 | 16 | 72 HB | 36 % IACS |
As built (as printed) | Pick for prototypes or when the print can be used directly; fine cellular structure gives moderate strength with high residual stress. | 230 | 300 | 6 | 82 HB | 33 % IACS |
Cooled from hot working and artificially aged | Pick when quench distortion must be avoided on large or thin-wall prints; gives part of the T6 strength gain with no solution quench. | 280 | 325 | 7 | 95 HB | 38 % IACS |
hot isostatic pressed then solution treated and aged | Specify for fatigue- or pressure-critical parts: HIP closes residual gas porosity and raises ductility and fatigue life at similar static strength. | 315 | 360 | 13 | 102 HB | 41 % IACS |
T6Default Solution heat treated and artificially aged | Standard supplied/qualified condition — highest strength with wrought-6061-T6-like properties; use for structural printed parts. | 330 | 370 | 9 | 105 HB | 40 % IACS |
What is A6061-RAM2?
A6061-RAM2 is a zirconium-nanoparticle-modified 6061 Al-Mg-Si chemistry engineered to eliminate hot cracking in LPBF. Engineers use it for printed parts that need wrought-6061-T6-like behaviour with good conductivity: 330 MPa yield, 370 MPa tensile, 9 % elongation, 105 HB, 155 W/m·K and 40 % IACS in the default condition, with AB, SR, T4, T5, T6 and HIP+T6 on file. It machines comparatively well (score 65) and welds, but service is limited to 150 °C and the hard dispersoids shorten tool life. A2024-RAM2 or A7075-RAM10 are the alternatives when higher strength is required. A6061-RAM2 has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 582°C (1,080 °F). A6061-RAM2 has a yield strength of 330 MPa (47.9 ksi) and a tensile strength of 370 MPa (53.7 ksi) — stronger than 81% of aluminum grades. Elongation at break is 9% and the elastic modulus is 73 GPa (10.6 Msi).

Working with A6061-RAM2
Is A6061-RAM2 easy to machine?
Machines much like 6061-T6 with sharp uncoated-carbide or polished-flute tools and flood coolant, but the hard nucleant/ceramic dispersoids are abrasive — expect shorter tool life than wrought 6061.
Can A6061-RAM2 be welded?
Weldable by TIG/laser with 4043 or 5356 filler; the nucleant addition strongly reduces the solidification-cracking tendency that limits plain 6061, though the HAZ still overages and needs re-solution + aging for full strength.
Can A6061-RAM2 be formed, bent or molded?
Print on a heated plate (≈150–200 °C) with a stress-relief cycle before build-plate removal; supports and thin walls should be designed for the T6 quench distortion, and only mild post-print straightening in T4 is advisable.

What surface finishes work on A6061-RAM2?
Bead-blast or machine the as-built skin before finishing; clear/hard anodize and chromate-free conversion coatings work but the dispersoids can give slight color mottling, so machine or polish cosmetic faces first.

A6061-RAM2 — frequently asked
What is A6061-RAM2 used for?
A6061-RAM2 is typically used for general engineering AM parts, automotive brackets and thermal management components. In short: weldable printed 6061; best thermal conductivity in family; easiest-machining LPBF aluminum.
What is the yield strength of A6061-RAM2?
A6061-RAM2 has a typical yield strength of 330 MPa (47.9 ksi) and a tensile strength of 370 MPa (53.7 ksi) — stronger than 81% of aluminum grades. Strength varies by condition: see the 6 listed tempers.
Is A6061-RAM2 easy to machine?
Reasonably — machinability is rated good (65/100, better than 62% of aluminum grades). Machines much like 6061-T6 with sharp uncoated-carbide or polished-flute tools and flood coolant, but the hard nucleant/ceramic dispersoids are abrasive — expect shorter tool life than wrought 6061.

What is the maximum service temperature of A6061-RAM2?
A6061-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.

T6 is the default condition — standard supplied/qualified condition — highest strength with wrought-6061-T6-like properties; use for structural printed parts. SR: use when distortion control and dimensional stability matter more than strength, e.g. before EDM cut-off or thin-wall heat exchangers. Yield strength is 330 MPa in T6 versus 165 MPa in SR.
