Aluminum 5083-H14 vs 5083-O
Aluminum · 5083 temper comparison
5083-H14 and 5083-O are two conditions of the same aluminum grade, 5083: H14 (strain hardened, half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 5083-H14 is the stronger of the two: yield strength 255 MPa (37 ksi) against 145 MPa (21 ksi) for 5083-O, about 76% more; tensile strength follows at 340 MPa (49.3 ksi) vs 290 MPa (42.1 ksi). In exchange, 5083-O is the more ductile: elongation 23% versus 9% for 5083-H14, and 5083-H14 is harder (90 HB vs 65 HB). 5083-O runs hotter in service (80°C vs 65°C continuous). On the shop floor, 5083-H14 machines more easily (50 vs 40 out of 100).
5083-H14Choose it when strength drives the design, or when the part is machined in volume.
5083-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5083-H14 vs 5083-O: 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.
