Aluminum 5026-H111 vs 5026-O
Aluminum · 5026 temper comparison
5026-H111 and 5026-O are two conditions of the same aluminum grade, 5026: H111 (slightly strain hardened) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 5026-H111 is the stronger of the two: yield strength 170 MPa (24.7 ksi) against 140 MPa (20.3 ksi) for 5026-O, about 21% more; tensile strength follows at 310 MPa (45 ksi) vs 290 MPa (42.1 ksi). In exchange, 5026-O is the more ductile: elongation 24% versus 18% for 5026-H111, and 5026-H111 is harder (80 HB vs 70 HB). On the shop floor, 5026-H111 machines more easily (45 vs 35 out of 100).
5026-H111Choose it when strength drives the design, or when the part is machined in volume.
5026-OChoose it when the part is bent, formed or impact-loaded.
5026-H111 vs 5026-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.

5026-H111 vs 5026-O — frequently asked
Is 5026-H111 stronger than 5026-O?
Yes. 5026-H111 has a typical yield strength of 170 MPa (24.7 ksi) against 140 MPa (20.3 ksi) for 5026-O — about 21% more. Tensile strength is 310 MPa (45 ksi) vs 290 MPa (42.1 ksi).
Which condition does FabDigit quote by default, H111 or O?
H111 is the default 5026 condition in the FabDigit quote flow. 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, 5026-H111 or 5026-O?
5026-H111, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for 5026-O.
