Aluminum A7075-RAM10 vs Scalmalloy
Aluminum · grade comparison
Aluminum A7075-RAM10 and Scalmalloy are both aluminum grades. A7075-RAM10 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 285 MPa (41.3 ksi) for Scalmalloy, about 68% more; tensile strength follows at 530 MPa (76.9 ksi) vs 400 MPa (58 ksi). In exchange, Scalmalloy is the more ductile: elongation 14% versus 6% for A7075-RAM10, and A7075-RAM10 is harder (155 HB vs 100 HB). Scalmalloy is lighter (2.67 g/cm³ vs 2.9 g/cm³ for A7075-RAM10) and A7075-RAM10 is stiffer (78 GPa vs 70 GPa). On the shop floor, Scalmalloy machines more easily (good vs fair), Scalmalloy welds better (good vs fair), and A7075-RAM10 sits in a lower cost tier (high, $$$$) than Scalmalloy (specialty, $$$$$).
A7075-RAM10Choose it when strength drives the design, or when the part sees heat.
ScalmalloyChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
A7075-RAM10 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.
