Aluminum 2060-T4 vs 2060-T8

Aluminum · 2060 temper comparison

2060-T4 and 2060-T8 are two conditions of the same aluminum grade, 2060: T4 (solution heat treated and naturally aged) 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 260 MPa (37.7 ksi) for 2060-T4, about 81% more; tensile strength follows at 500 MPa (72.5 ksi) vs 430 MPa (62.4 ksi). In exchange, 2060-T4 is the more ductile: elongation 12% versus 10% for 2060-T8, and 2060-T8 is harder (150 HB vs 90 HB). 2060-T8 is stiffer (78 GPa vs 70 GPa) and 2060-T8 runs hotter in service (150°C vs 100°C continuous). On the shop floor, 2060-T4 machines more easily (very good vs good) and 2060-T4 welds better (fair vs poor).

2060-T4Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

2060-T8Choose it when strength drives the design, or when the part sees heat.

2060-T4 vs 2060-T8 — frequently asked

Is 2060-T8 stronger than 2060-T4?

Yes. 2060-T8 has a typical yield strength of 470 MPa (68.2 ksi) against 260 MPa (37.7 ksi) for 2060-T4 — about 81% more. Tensile strength is 500 MPa (72.5 ksi) vs 430 MPa (62.4 ksi).

Which condition does FabDigit quote by default, T4 or T8?

T81 is the default 2060 condition in the FabDigit quote flow (neither T4 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-T4 or 2060-T8?

2060-T4. Its machinability rates very good (70/100) against good (60/100) for 2060-T8; for welding the order is 2060-T4 first (fair, 40/100) then 2060-T8 (poor, 20/100).
