Aluminum A7075-RAM10 vs AlMgSc
Aluminum · grade comparison
Aluminum A7075-RAM10 and AlMgSc are both aluminum grades. A7075-RAM10 is the stronger of the two: tensile strength 530 MPa (76.9 ksi) against 500 MPa (72.5 ksi) for AlMgSc, about 6% more. In exchange, AlMgSc is the more ductile: elongation 12% versus 6% for A7075-RAM10, and A7075-RAM10 is harder (155 HB vs 140 HB). AlMgSc 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, AlMgSc machines more easily (good vs fair) and AlMgSc welds better (excellent vs fair).

A7075-RAM10 vs AlMgSc: 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.

A7075-RAM10 vs AlMgSc — frequently asked
Is A7075-RAM10 stronger than AlMgSc?
Yes. A7075-RAM10 has a typical tensile strength of 530 MPa (76.9 ksi) against 500 MPa (72.5 ksi) for AlMgSc — about 6% more.
Which is cheaper, A7075-RAM10 or AlMgSc?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, A7075-RAM10 or AlMgSc?
AlMgSc. Its machinability rates good (55/100) against fair (45/100) for A7075-RAM10; for welding the order is AlMgSc first (excellent, 85/100) then A7075-RAM10 (fair, 45/100).
