Aluminum 7010-O vs 7010-T6
Aluminum · 7010 temper comparison
7010-O and 7010-T6 are two conditions of the same aluminum grade, 7010: O (annealed) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. 7010-T6 is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 110 MPa (16 ksi) for 7010-O, about 4.5 times as much; tensile strength follows at 560 MPa (81.2 ksi) vs 240 MPa (34.8 ksi). In exchange, 7010-O is the more ductile: elongation 16% versus 8% for 7010-T6, and 7010-T6 is harder (160 HB vs 65 HB). 7010-O runs hotter in service (150°C vs 100°C continuous) and 7010-O conducts heat better (175 W/m·K vs 130 W/m·K). On the shop floor, 7010-T6 machines more easily (very good vs fair).
7010-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
7010-T6Choose it when strength drives the design, or when the part is machined in volume.
7010-O vs 7010-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.

7010-O vs 7010-T6 — frequently asked
Is 7010-T6 stronger than 7010-O?
Yes. 7010-T6 has a typical yield strength of 500 MPa (72.5 ksi) against 110 MPa (16 ksi) for 7010-O — about 4.5 times as much. Tensile strength is 560 MPa (81.2 ksi) vs 240 MPa (34.8 ksi).
Which condition does FabDigit quote by default, O or T6?
Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.
Which is easier to machine, 7010-O or 7010-T6?
7010-T6. Its machinability rates very good (75/100) against fair (50/100) for 7010-O.
