Aluminum 3003-H112 vs 3003-H22
Aluminum · 3003 temper comparison
3003-H112 and 3003-H22 are two conditions of the same aluminum grade, 3003: H112 (strain hardened from hot working only) versus H22 (strain hardened and partially annealed, quarter hard). The chemistry is identical, so every difference below comes from the condition. 3003-H22 is the stronger of the two: yield strength 115 MPa (16.7 ksi) against 55 MPa (7.98 ksi) for 3003-H112, about 109% more; tensile strength follows at 140 MPa (20.3 ksi) vs 120 MPa (17.4 ksi). In exchange, 3003-H112 is the more ductile: elongation 25% versus 14% for 3003-H22, and 3003-H22 is harder (35 HB vs 30 HB).
3003-H112Choose it when the part is bent, formed or impact-loaded.
3003-H22Choose it when strength drives the design.
3003-H112 vs 3003-H22: 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.
