Aluminum 5182-H111 vs 5182-O
Aluminum · 5182 temper comparison
5182-H111 and 5182-O are two conditions of the same aluminum grade, 5182: H111 (slightly strain hardened) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 5182-H111 is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 130 MPa (18.9 ksi) for 5182-O, about 15% more; tensile strength follows at 290 MPa (42.1 ksi) vs 275 MPa (39.9 ksi). 5182-H111 is harder — 75 HB against 70 HB for 5182-O — which matters for wear surfaces and threads.
5182-H111Choose it when strength drives the design, or when surface hardness matters.
5182-H111 vs 5182-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.
