Aluminum 5154A-H111 vs 5154A-H14
Aluminum · 5154A temper comparison
5154A-H111 and 5154A-H14 are two conditions of the same aluminum grade, 5154A: H111 (slightly strain hardened) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. 5154A-H14 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 105 MPa (15.2 ksi) for 5154A-H111, about 133% more; tensile strength follows at 285 MPa (41.3 ksi) vs 230 MPa (33.4 ksi). In exchange, 5154A-H111 is the more ductile: elongation 22% versus 6% for 5154A-H14, and 5154A-H14 is harder (75 HB vs 60 HB). 5154A-H111 runs hotter in service (90°C vs 65°C continuous). On the shop floor, 5154A-H14 machines more easily (48 vs 36 out of 100).
5154A-H111Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5154A-H14Choose it when strength drives the design, or when the part is machined in volume.
5154A-H111 vs 5154A-H14: 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.

5154A-H111 vs 5154A-H14 — frequently asked
Is 5154A-H14 stronger than 5154A-H111?
Yes. 5154A-H14 has a typical yield strength of 245 MPa (35.5 ksi) against 105 MPa (15.2 ksi) for 5154A-H111 — about 133% more. Tensile strength is 285 MPa (41.3 ksi) vs 230 MPa (33.4 ksi).
Which condition does FabDigit quote by default, H111 or H14?
H22 is the default 5154A condition in the FabDigit quote flow (neither H111 nor H14). 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, 5154A-H111 or 5154A-H14?
5154A-H14, by a small margin. Both rate fair for machinability — 48/100 against 36/100 for 5154A-H111.
