Aluminum 2014A-O vs 2014A-T6
Aluminum · 2014A temper comparison
2014A-O and 2014A-T6 are two conditions of the same aluminum grade, 2014A: O (annealed) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. 2014A-T6 is the stronger of the two: yield strength 414 MPa (60 ksi) against 95 MPa (13.8 ksi) for 2014A-O, about 4.4 times as much; tensile strength follows at 483 MPa (70.1 ksi) vs 185 MPa (26.8 ksi). In exchange, 2014A-O is the more ductile: elongation 18% versus 11% for 2014A-T6, and 2014A-T6 is harder (135 HB vs 45 HB). 2014A-O runs hotter in service (200°C vs 150°C continuous) and 2014A-O conducts heat better (190 W/m·K vs 155 W/m·K). On the shop floor, 2014A-T6 machines more easily (very good vs fair) and 2014A-O welds better (fair vs poor).
2014A-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
2014A-T6Choose it when strength drives the design, or when the part is machined in volume.
2014A-O vs 2014A-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.

2014A-O vs 2014A-T6 — frequently asked
Is 2014A-T6 stronger than 2014A-O?
Yes. 2014A-T6 has a typical yield strength of 414 MPa (60 ksi) against 95 MPa (13.8 ksi) for 2014A-O — about 4.4 times as much. Tensile strength is 483 MPa (70.1 ksi) vs 185 MPa (26.8 ksi).
Which condition does FabDigit quote by default, O or T6?
T651 is the default 2014A condition in the FabDigit quote flow (neither O 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, 2014A-O or 2014A-T6?
2014A-T6. Its machinability rates very good (80/100) against fair (45/100) for 2014A-O; for welding the order is 2014A-O first (fair, 35/100) then 2014A-T6 (poor, 25/100).
