Aluminum 5083-H112 vs 5083-H34
Aluminum · 5083 temper comparison
5083-H112 and 5083-H34 are two conditions of the same aluminum grade, 5083: H112 (strain hardened from hot working only) versus H34 (strain hardened and stabilized, half hard). The chemistry is identical, so every difference below comes from the condition. 5083-H34 is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 165 MPa (23.9 ksi) for 5083-H112, about 67% more; tensile strength follows at 345 MPa (50 ksi) vs 300 MPa (43.5 ksi). In exchange, 5083-H112 is the more ductile: elongation 16% versus 9% for 5083-H34, and 5083-H34 is harder (90 HB vs 72 HB). 5083-H34 runs hotter in service (80°C vs 65°C continuous).
5083-H112Choose it when the part is bent, formed or impact-loaded.
5083-H34Choose it when strength drives the design, or when the part sees heat.
5083-H112 vs 5083-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.
