Aluminum 2090-F vs 2090-T3
Aluminum · 2090 temper comparison
2090-F and 2090-T3 are two conditions of the same aluminum grade, 2090: F (as fabricated) versus T3 (solution heat treated, cold worked and naturally aged). The chemistry is identical, so every difference below comes from the condition. 2090-T3 is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 170 MPa (24.7 ksi) for 2090-F, about 53% more; tensile strength follows at 380 MPa (55.1 ksi) vs 280 MPa (40.6 ksi). In exchange, 2090-F is the more ductile: elongation 14% versus 12% for 2090-T3, and 2090-T3 is harder (105 HB vs 80 HB). 2090-F runs hotter in service (150°C vs 120°C continuous).
2090-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
2090-T3Choose it when strength drives the design.
2090-F vs 2090-T3: 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.

2090-F vs 2090-T3 — frequently asked
Is 2090-T3 stronger than 2090-F?
Yes. 2090-T3 has a typical yield strength of 260 MPa (37.7 ksi) against 170 MPa (24.7 ksi) for 2090-F — about 53% more. Tensile strength is 380 MPa (55.1 ksi) vs 280 MPa (40.6 ksi).
Which condition does FabDigit quote by default, F or T3?
T83 is the default 2090 condition in the FabDigit quote flow (neither F nor T3). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 2090-F or 2090-T3?
2090-T3. Its machinability rates good (55/100) against fair (48/100) for 2090-F.
