Aluminum 1100-H112 vs 1100-H19
Aluminum · 1100 temper comparison
1100-H112 and 1100-H19 are two conditions of the same aluminum grade, 1100: H112 (strain hardened from hot working only) versus H19 (strain hardened, extra hard). The chemistry is identical, so every difference below comes from the condition. 1100-H19 is the stronger of the two: yield strength 170 MPa (24.7 ksi) against 45 MPa (6.53 ksi) for 1100-H112, about 3.8 times as much; tensile strength follows at 185 MPa (26.8 ksi) vs 95 MPa (13.8 ksi). In exchange, 1100-H112 is the more ductile: elongation 25% versus 3% for 1100-H19, and 1100-H19 is harder (48 HB vs 25 HB). 1100-H112 runs hotter in service (200°C vs 100°C continuous). On the shop floor, 1100-H19 machines more easily (fair vs poor).
1100-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1100-H19Choose it when strength drives the design, or when the part is machined in volume.
1100-H112 vs 1100-H19: 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.
