Aluminum 5182-H111 vs 5182-H38
Aluminum · 5182 temper comparison
5182-H111 and 5182-H38 are two conditions of the same aluminum grade, 5182: H111 (slightly strain hardened) versus H38 (strain hardened and stabilized, full hard). The chemistry is identical, so every difference below comes from the condition. 5182-H38 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 150 MPa (21.8 ksi) for 5182-H111, about 120% more; tensile strength follows at 385 MPa (55.8 ksi) vs 290 MPa (42.1 ksi). In exchange, 5182-H111 is the more ductile: elongation 19% versus 6% for 5182-H38, and 5182-H38 is harder (100 HB vs 75 HB). 5182-H38 runs hotter in service (80°C vs 65°C continuous). On the shop floor, 5182-H38 machines more easily (48 vs 38 out of 100).
5182-H111Choose it when the part is bent, formed or impact-loaded.
5182-H38Choose it when strength drives the design, or when the part sees heat.
5182-H111 vs 5182-H38: 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.
