Aluminum 5183-AW vs 5183-O
Aluminum · 5183 temper comparison
5183-AW and 5183-O are two conditions of the same aluminum grade, 5183: AW (as-welded deposit) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 5183-AW is the stronger of the two: yield strength 165 MPa (23.9 ksi) against 130 MPa (18.9 ksi) for 5183-O, about 27% more; tensile strength follows at 315 MPa (45.7 ksi) vs 285 MPa (41.3 ksi). On the shop floor, 5183-O forms better (very good vs good).

5183-AW vs 5183-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.
