Aluminum A6061-RAM2 vs Scalmalloy
Aluminum · grade comparison
Aluminum A6061-RAM2 and Scalmalloy are both aluminum grades. A6061-RAM2 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 285 MPa (41.3 ksi) for Scalmalloy, about 16% more. In exchange, Scalmalloy is the more ductile: elongation 14% versus 9% for A6061-RAM2, and A6061-RAM2 is harder (115 HV vs 105 HV). A6061-RAM2 runs hotter in service (150°C vs 120°C continuous) and A6061-RAM2 conducts heat better (155 W/m·K vs 110 W/m·K). On the shop floor, A6061-RAM2 machines more easily (65 vs 55 out of 100) and A6061-RAM2 sits in a lower cost tier (high, $$$$) than Scalmalloy (specialty, $$$$$).

A6061-RAM2 vs Scalmalloy: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
