Aluminum 2030 vs 2090
Aluminum · grade comparison
Aluminum 2030 and 2090 are both aluminum grades. 2090 is the stronger of the two: yield strength 517 MPa (75 ksi) against 285 MPa (41.3 ksi) for 2030, about 81% more; tensile strength follows at 550 MPa (79.8 ksi) vs 400 MPa (58 ksi). In exchange, 2030 is the more ductile: elongation 12% versus 6% for 2090, and 2090 is harder (150 HB vs 100 HB). 2090 is lighter (2.59 g/cm³ vs 2.82 g/cm³ for 2030) and 2090 runs hotter in service (150°C vs 100°C continuous). On the shop floor, 2030 machines more easily (excellent vs good), 2090 welds better (poor vs not recommended), and 2030 sits in a lower cost tier (premium, $$$) than 2090 (high, $$$$).
2030Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
2090Choose it when strength drives the design, or when weight is the constraint.
2030 vs 2090: 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.

2030 vs 2090 — frequently asked
Is 2090 stronger than 2030?
Yes. 2090 has a typical yield strength of 517 MPa (75 ksi) against 285 MPa (41.3 ksi) for 2030 — about 81% more. Tensile strength is 550 MPa (79.8 ksi) vs 400 MPa (58 ksi).
Which is cheaper, 2030 or 2090?
2030 is the lower-cost material: it sits in the premium tier ($$$) while 2090 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 2030 or 2090?
2030. Its machinability rates excellent (92/100) against good (62/100) for 2090; for welding the order is 2090 first (poor, 25/100) then 2030 (not recommended, 12/100).
