Aluminum 6110A-F vs 6110A-T4
Aluminum · 6110A temper comparison
6110A-F and 6110A-T4 are two conditions of the same aluminum grade, 6110A: F (as fabricated) versus T4 (solution heat treated and naturally aged). The chemistry is identical, so every difference below comes from the condition. 6110A-T4 is the stronger of the two: yield strength 155 MPa (22.5 ksi) against 110 MPa (16 ksi) for 6110A-F, about 41% more; tensile strength follows at 260 MPa (37.7 ksi) vs 200 MPa (29 ksi). 6110A-T4 is the more ductile: elongation 20% versus 18% for 6110A-F, and 6110A-T4 is harder (75 HB vs 55 HB). 6110A-F runs hotter in service (200°C vs 100°C continuous) and 6110A-F conducts heat better (170 W/m·K vs 150 W/m·K).
6110A-FChoose it when the part sees heat.
6110A-T4Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
6110A-F vs 6110A-T4: 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.

6110A-F vs 6110A-T4 — frequently asked
Is 6110A-T4 stronger than 6110A-F?
Yes. 6110A-T4 has a typical yield strength of 155 MPa (22.5 ksi) against 110 MPa (16 ksi) for 6110A-F — about 41% more. Tensile strength is 260 MPa (37.7 ksi) vs 200 MPa (29 ksi).
Which condition does FabDigit quote by default, F or T4?
T6 is the default 6110A condition in the FabDigit quote flow (neither F nor T4). 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, 6110A-F or 6110A-T4?
6110A-T4, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 6110A-F.
