Aluminum 5082-H111 vs 5082-H14
Aluminum · 5082 temper comparison
5082-H111 and 5082-H14 are two conditions of the same aluminum grade, 5082: H111 (slightly strain hardened) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. 5082-H14 is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 140 MPa (20.3 ksi) for 5082-H111, about 86% more; tensile strength follows at 330 MPa (47.9 ksi) vs 275 MPa (39.9 ksi). In exchange, 5082-H111 is the more ductile: elongation 20% versus 9% for 5082-H14, and 5082-H14 is harder (85 HB vs 66 HB). On the shop floor, 5082-H14 machines more easily (good vs fair).
5082-H111Choose it when the part is bent, formed or impact-loaded.
5082-H14Choose it when strength drives the design, or when the part is machined in volume.
5082-H111 vs 5082-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.
