Aluminum 7093-F vs 7093-T76
Aluminum · 7093 temper comparison
7093-F and 7093-T76 are two conditions of the same aluminum grade, 7093: F (as fabricated) versus T76 (overaged for exfoliation-corrosion resistance). The chemistry is identical, so every difference below comes from the condition. 7093-T76 is the stronger of the two: yield strength 600 MPa (87 ksi) against 290 MPa (42.1 ksi) for 7093-F, about 107% more; tensile strength follows at 655 MPa (95 ksi) vs 400 MPa (58 ksi). 7093-T76 is harder — 168 HB against 110 HB for 7093-F — which matters for wear surfaces and threads. On the shop floor, 7093-T76 machines more easily (68 vs 55 out of 100) and 7093-F forms better (fair vs poor).
7093-T76Choose it when strength drives the design, or when surface hardness matters.
7093-F vs 7093-T76: 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.

7093-F vs 7093-T76 — frequently asked
Is 7093-T76 stronger than 7093-F?
Yes. 7093-T76 has a typical yield strength of 600 MPa (87 ksi) against 290 MPa (42.1 ksi) for 7093-F — about 107% more. Tensile strength is 655 MPa (95 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, F or T76?
T6 is the default 7093 condition in the FabDigit quote flow (neither F nor T76). 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, 7093-F or 7093-T76?
7093-T76, by a small margin. Both rate good for machinability — 68/100 against 55/100 for 7093-F.
