Aluminum 7095-F vs 7095-T7351
Aluminum · 7095 temper comparison
7095-F and 7095-T7351 are two conditions of the same aluminum grade, 7095: F (as fabricated) versus T7351 (T73, stress relieved by stretching). The chemistry is identical, so every difference below comes from the condition. 7095-T7351 is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 250 MPa (36.3 ksi) for 7095-F, about 128% more; tensile strength follows at 620 MPa (89.9 ksi) vs 380 MPa (55.1 ksi). 7095-T7351 is harder — 163 HB against 110 HB for 7095-F — which matters for wear surfaces and threads. On the shop floor, 7095-T7351 machines more easily (66 vs 55 out of 100) and 7095-F forms better (fair vs poor).
7095-T7351Choose it when strength drives the design, or when surface hardness matters.
7095-F vs 7095-T7351: 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.

7095-F vs 7095-T7351 — frequently asked
Is 7095-T7351 stronger than 7095-F?
Yes. 7095-T7351 has a typical yield strength of 570 MPa (82.7 ksi) against 250 MPa (36.3 ksi) for 7095-F — about 128% more. Tensile strength is 620 MPa (89.9 ksi) vs 380 MPa (55.1 ksi).
Which condition does FabDigit quote by default, F or T7351?
T651 is the default 7095 condition in the FabDigit quote flow (neither F nor T7351). 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, 7095-F or 7095-T7351?
7095-T7351, by a small margin. Both rate good for machinability — 66/100 against 55/100 for 7095-F; for welding the order is 7095-F first (poor, 20/100) then 7095-T7351 (poor, 15/100).
