Aluminum 5110A-H111 vs 5110A-H26
Aluminum · 5110A temper comparison
5110A-H111 and 5110A-H26 are two conditions of the same aluminum grade, 5110A: H111 (slightly strain hardened) versus H26 (strain hardened and partially annealed, three-quarter hard). The chemistry is identical, so every difference below comes from the condition. 5110A-H26 is the stronger of the two: yield strength 125 MPa (18.1 ksi) against 50 MPa (7.25 ksi) for 5110A-H111, about 150% more; tensile strength follows at 150 MPa (21.8 ksi) vs 110 MPa (16 ksi). In exchange, 5110A-H111 is the more ductile: elongation 20% versus 6% for 5110A-H26, and 5110A-H26 is harder (44 HB vs 30 HB). 5110A-H111 runs hotter in service (180°C vs 150°C continuous). On the shop floor, 5110A-H26 machines more easily (fair vs poor).
5110A-H111Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5110A-H26Choose it when strength drives the design, or when the part is machined in volume.
5110A-H111 vs 5110A-H26: 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.

5110A-H111 vs 5110A-H26 — frequently asked
Is 5110A-H26 stronger than 5110A-H111?
Yes. 5110A-H26 has a typical yield strength of 125 MPa (18.1 ksi) against 50 MPa (7.25 ksi) for 5110A-H111 — about 150% more. Tensile strength is 150 MPa (21.8 ksi) vs 110 MPa (16 ksi).
Which condition does FabDigit quote by default, H111 or H26?
H14 is the default 5110A condition in the FabDigit quote flow (neither H111 nor H26). 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, 5110A-H111 or 5110A-H26?
5110A-H26. Its machinability rates fair (42/100) against poor (28/100) for 5110A-H111; for welding the order is 5110A-H111 first (excellent, 90/100) then 5110A-H26 (excellent, 85/100).
