Aluminum 1080-H111 vs 1080-O
Aluminum · 1080 temper comparison
1080-H111 and 1080-O are two conditions of the same aluminum grade, 1080: H111 (slightly strain hardened) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 1080-H111 is the stronger of the two: yield strength 28 MPa (4.06 ksi) against 25 MPa (3.63 ksi) for 1080-O, about 12% more; tensile strength follows at 75 MPa (10.9 ksi) vs 70 MPa (10.2 ksi). In exchange, 1080-O is the more ductile: elongation 43% versus 38% for 1080-H111.
1080-H111Choose it when strength drives the design.
1080-OChoose it when the part is bent, formed or impact-loaded.
1080-H111 vs 1080-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.

1080-H111 vs 1080-O — frequently asked
Is 1080-H111 stronger than 1080-O?
Yes. 1080-H111 has a typical yield strength of 28 MPa (4.06 ksi) against 25 MPa (3.63 ksi) for 1080-O — about 12% more. Tensile strength is 75 MPa (10.9 ksi) vs 70 MPa (10.2 ksi).
Which condition does FabDigit quote by default, H111 or O?
Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.
When should I choose 1080-H111 over 1080-O?
Pick 1080-H111 when strength drives the design. Pick 1080-O when the part is bent, formed or impact-loaded.
