Aluminum 5154-H111 vs 5154-H34
Aluminum · 5154 temper comparison
5154-H111 and 5154-H34 are two conditions of the same aluminum grade, 5154: H111 (slightly strain hardened) versus H34 (strain hardened and stabilized, half hard). The chemistry is identical, so every difference below comes from the condition. 5154-H34 is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 130 MPa (18.9 ksi) for 5154-H111, about 77% more; tensile strength follows at 290 MPa (42.1 ksi) vs 245 MPa (35.5 ksi). In exchange, 5154-H111 is the more ductile: elongation 22% versus 13% for 5154-H34, and 5154-H34 is harder (73 HB vs 60 HB). 5154-H111 runs hotter in service (100°C vs 65°C continuous). On the shop floor, 5154-H34 machines more easily (48 vs 38 out of 100).
5154-H111Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5154-H34Choose it when strength drives the design, or when the part is machined in volume.
5154-H111 vs 5154-H34: 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.
