Aluminum 8011-H14 vs 8011-O
Aluminum · 8011 temper comparison
8011-H14 and 8011-O are two conditions of the same aluminum grade, 8011: H14 (strain hardened, half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 8011-H14 is the stronger of the two: yield strength 120 MPa (17.4 ksi) against 40 MPa (5.8 ksi) for 8011-O, about 3.0 times as much; tensile strength follows at 145 MPa (21 ksi) vs 95 MPa (13.8 ksi). In exchange, 8011-O is the more ductile: elongation 25% versus 4% for 8011-H14, and 8011-H14 is harder (42 HB vs 24 HB).
8011-H14Choose it when strength drives the design.
8011-OChoose it when the part is bent, formed or impact-loaded.
8011-H14 vs 8011-O: 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.

8011-H14 vs 8011-O — frequently asked
Is 8011-H14 stronger than 8011-O?
Yes. 8011-H14 has a typical yield strength of 120 MPa (17.4 ksi) against 40 MPa (5.8 ksi) for 8011-O — about 3.0 times as much. Tensile strength is 145 MPa (21 ksi) vs 95 MPa (13.8 ksi).
Which condition does FabDigit quote by default, H14 or O?
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, 8011-H14 or 8011-O?
8011-H14, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for 8011-O.
