Aluminum 2008 vs 2030
Aluminum · grade comparison
Aluminum 2008 and 2030 are both aluminum grades. 2030 is the stronger of the two: yield strength 285 MPa (41.3 ksi) against 125 MPa (18.1 ksi) for 2008, about 128% more; tensile strength follows at 400 MPa (58 ksi) vs 240 MPa (34.8 ksi). In exchange, 2008 is the more ductile: elongation 28% versus 12% for 2030, and 2030 is harder (100 HB vs 65 HB). 2008 is lighter (2.72 g/cm³ vs 2.82 g/cm³ for 2030) and 2008 runs hotter in service (120°C vs 100°C continuous). On the shop floor, 2030 machines more easily (excellent vs good) and 2008 welds better (fair vs not recommended).
2008Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
2030Choose it when strength drives the design, or when the part is machined in volume.
2008 vs 2030: 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.

2008 vs 2030 — frequently asked
Is 2030 stronger than 2008?
Yes. 2030 has a typical yield strength of 285 MPa (41.3 ksi) against 125 MPa (18.1 ksi) for 2008 — about 128% more. Tensile strength is 400 MPa (58 ksi) vs 240 MPa (34.8 ksi).
Which is cheaper, 2008 or 2030?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 2008 or 2030?
2030. Its machinability rates excellent (92/100) against good (55/100) for 2008; for welding the order is 2008 first (fair, 35/100) then 2030 (not recommended, 12/100).
