Aluminum 7095-F vs 7095-T651
Aluminum · 7095 temper comparison
7095-F and 7095-T651 are two conditions of the same aluminum grade, 7095: F (as fabricated) versus T651 (T6, stress relieved by stretching). The chemistry is identical, so every difference below comes from the condition. 7095-T651 is the stronger of the two: yield strength 675 MPa (97.9 ksi) against 250 MPa (36.3 ksi) for 7095-F, about 170% more; tensile strength follows at 710 MPa (103 ksi) vs 380 MPa (55.1 ksi). In exchange, 7095-F is the more ductile: elongation 12% versus 10% for 7095-T651, and 7095-T651 is harder (190 HB vs 110 HB). 7095-F runs hotter in service (150°C vs 120°C continuous) and 7095-F conducts heat better (155 W/m·K vs 135 W/m·K). On the shop floor, 7095-T651 machines more easily (very good vs good).
7095-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
7095-T651Choose it when strength drives the design, or when the part is machined in volume.
7095-F vs 7095-T651: 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-T651 — frequently asked
Is 7095-T651 stronger than 7095-F?
Yes. 7095-T651 has a typical yield strength of 675 MPa (97.9 ksi) against 250 MPa (36.3 ksi) for 7095-F — about 170% more. Tensile strength is 710 MPa (103 ksi) vs 380 MPa (55.1 ksi).
Which condition does FabDigit quote by default, F or T651?
T651 is the default 7095 condition in the FabDigit quote flow. 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-T651?
7095-T651. Its machinability rates very good (70/100) against good (55/100) for 7095-F; for welding the order is 7095-F first (poor, 20/100) then 7095-T651 (poor, 15/100).
