Aluminum 2060-T4 vs 2060-T6
Aluminum · 2060 temper comparison
2060-T4 and 2060-T6 are two conditions of the same aluminum grade, 2060: T4 (solution heat treated and naturally aged) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. 2060-T6 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 260 MPa (37.7 ksi) for 2060-T4, about 46% more. In exchange, 2060-T4 is the more ductile: elongation 12% versus 6% for 2060-T6, and 2060-T6 is harder (120 HB vs 90 HB). 2060-T6 runs hotter in service (150°C vs 100°C continuous).
2060-T4Choose it when the part is bent, formed or impact-loaded.
2060-T6Choose it when strength drives the design, or when the part sees heat.
2060-T4 vs 2060-T6: 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-T4 vs 2060-T6 — frequently asked
Is 2060-T6 stronger than 2060-T4?
Yes. 2060-T6 has a typical yield strength of 380 MPa (55.1 ksi) against 260 MPa (37.7 ksi) for 2060-T4 — about 46% more. Tensile strength is 450 MPa (65.3 ksi) vs 430 MPa (62.4 ksi).
Which condition does FabDigit quote by default, T4 or T6?
T81 is the default 2060 condition in the FabDigit quote flow (neither T4 nor T6). 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-T4 or 2060-T6?
2060-T6, by a small margin. Both rate very good for machinability — 75/100 against 70/100 for 2060-T4; for welding the order is 2060-T4 first (fair, 40/100) then 2060-T6 (fair, 35/100).
