Aluminum A2024-RAM2 vs AlSi7Mg0.6
Aluminum · grade comparison
Aluminum A2024-RAM2 and AlSi7Mg0.6 are both aluminum grades. A2024-RAM2 is the stronger of the two: yield strength 430 MPa (62.4 ksi) against 285 MPa (41.3 ksi) for AlSi7Mg0.6, about 51% more; tensile strength follows at 500 MPa (72.5 ksi) vs 355 MPa (51.5 ksi). In exchange, AlSi7Mg0.6 is the more ductile: elongation 10% versus 6% for A2024-RAM2, and A2024-RAM2 is harder (140 HB vs 105 HB). AlSi7Mg0.6 is lighter (2.67 g/cm³ vs 2.78 g/cm³ for A2024-RAM2) and A2024-RAM2 is stiffer (78 GPa vs 72 GPa). On the shop floor, AlSi7Mg0.6 machines more easily (65 vs 55 out of 100) and AlSi7Mg0.6 welds better (good vs poor).
A2024-RAM2Choose it when strength drives the design.
AlSi7Mg0.6Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
A2024-RAM2 vs AlSi7Mg0.6: 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.

A2024-RAM2 vs AlSi7Mg0.6 — frequently asked
Is A2024-RAM2 stronger than AlSi7Mg0.6?
Yes. A2024-RAM2 has a typical yield strength of 430 MPa (62.4 ksi) against 285 MPa (41.3 ksi) for AlSi7Mg0.6 — about 51% more. Tensile strength is 500 MPa (72.5 ksi) vs 355 MPa (51.5 ksi).
Which is cheaper, A2024-RAM2 or AlSi7Mg0.6?
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, A2024-RAM2 or AlSi7Mg0.6?
AlSi7Mg0.6, by a small margin. Both rate good for machinability — 65/100 against 55/100 for A2024-RAM2; for welding the order is AlSi7Mg0.6 first (good, 65/100) then A2024-RAM2 (poor, 25/100).
