Aluminum 5182-H19 vs 5182-O
Aluminum · 5182 temper comparison
5182-H19 and 5182-O are two conditions of the same aluminum grade, 5182: H19 (strain hardened, extra hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 5182-H19 is the stronger of the two: yield strength 395 MPa (57.3 ksi) against 130 MPa (18.9 ksi) for 5182-O, about 3.0 times as much; tensile strength follows at 420 MPa (60.9 ksi) vs 275 MPa (39.9 ksi). In exchange, 5182-O is the more ductile: elongation 21% versus 4% for 5182-H19, and 5182-H19 is harder (110 HB vs 70 HB). On the shop floor, 5182-H19 machines more easily (50 vs 35 out of 100).
5182-H19Choose it when strength drives the design, or when the part is machined in volume.
5182-OChoose it when the part is bent, formed or impact-loaded.
5182-H19 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.
