Aluminum 7010-T6 vs 7010-T73
Aluminum · 7010 temper comparison
7010-T6 and 7010-T73 are two conditions of the same aluminum grade, 7010: T6 (solution heat treated and artificially aged) versus T73 (solution heat treated and overaged for stress-corrosion resistance). 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 420 MPa (60.9 ksi) for 7010-T73, about 19% more; tensile strength follows at 560 MPa (81.2 ksi) vs 490 MPa (71.1 ksi). In exchange, 7010-T73 is the more ductile: elongation 10% versus 8% for 7010-T6, and 7010-T6 is harder (160 HB vs 140 HB). 7010-T73 runs hotter in service (150°C vs 100°C continuous) and 7010-T73 conducts heat better (157 W/m·K vs 130 W/m·K).
7010-T6Choose it when strength drives the design.
7010-T73Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
7010-T6 vs 7010-T73: 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-T6 vs 7010-T73 — frequently asked
Is 7010-T6 stronger than 7010-T73?
Yes. 7010-T6 has a typical yield strength of 500 MPa (72.5 ksi) against 420 MPa (60.9 ksi) for 7010-T73 — about 19% more. Tensile strength is 560 MPa (81.2 ksi) vs 490 MPa (71.1 ksi).
Which condition does FabDigit quote by default, T6 or T73?
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-T6 or 7010-T73?
7010-T6, by a small margin. Both rate very good for machinability — 75/100 against 70/100 for 7010-T73.
