Aluminum 5154-H112 vs 5154-H14
Aluminum · 5154 temper comparison
5154-H112 and 5154-H14 are two conditions of the same aluminum grade, 5154: H112 (strain hardened from hot working only) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. 5154-H14 is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 125 MPa (18.1 ksi) for 5154-H112, about 76% more; tensile strength follows at 275 MPa (39.9 ksi) vs 240 MPa (34.8 ksi). In exchange, 5154-H112 is the more ductile: elongation 25% versus 13% for 5154-H14, and 5154-H14 is harder (70 HB vs 60 HB). On the shop floor, 5154-H14 machines more easily (good vs fair).
5154-H112Choose it when the part is bent, formed or impact-loaded.
5154-H14Choose it when strength drives the design, or when the part is machined in volume.
5154-H112 vs 5154-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.
