Aluminum 2060-T7 vs 2060-T8
Aluminum · 2060 temper comparison
2060-T7 and 2060-T8 are two conditions of the same aluminum grade, 2060: T7 (solution heat treated and overaged (stabilized)) versus T8 (solution heat treated, cold worked and artificially aged). The chemistry is identical, so every difference below comes from the condition. 2060-T8 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 345 MPa (50 ksi) for 2060-T7, about 36% more; tensile strength follows at 500 MPa (72.5 ksi) vs 435 MPa (63.1 ksi). 2060-T8 is harder — 150 HB against 105 HB for 2060-T7 — which matters for wear surfaces and threads. 2060-T8 is stiffer (78 GPa vs 70 GPa) and 2060-T7 runs hotter in service (200°C vs 150°C continuous). On the shop floor, 2060-T7 machines more easily (very good vs good) and 2060-T7 welds better (fair vs poor).
2060-T7Choose it when the part sees heat, or when the part is machined in volume.
2060-T8Choose it when strength drives the design, or when surface hardness matters.
2060-T7 vs 2060-T8: 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.

2060-T7 vs 2060-T8 — frequently asked
Is 2060-T8 stronger than 2060-T7?
Yes. 2060-T8 has a typical yield strength of 470 MPa (68.2 ksi) against 345 MPa (50 ksi) for 2060-T7 — about 36% more. Tensile strength is 500 MPa (72.5 ksi) vs 435 MPa (63.1 ksi).
Which condition does FabDigit quote by default, T7 or T8?
T81 is the default 2060 condition in the FabDigit quote flow (neither T7 nor T8). 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, 2060-T7 or 2060-T8?
2060-T7. Its machinability rates very good (72/100) against good (60/100) for 2060-T8; for welding the order is 2060-T7 first (fair, 40/100) then 2060-T8 (poor, 20/100).
