Aluminum 1070-H112 vs 1070-H14
Aluminum · 1070 temper comparison
1070-H112 and 1070-H14 are two conditions of the same aluminum grade, 1070: H112 (strain hardened from hot working only) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. 1070-H14 is the stronger of the two: yield strength 92 MPa (13.3 ksi) against 40 MPa (5.8 ksi) for 1070-H112, about 130% more; tensile strength follows at 105 MPa (15.2 ksi) vs 80 MPa (11.6 ksi). In exchange, 1070-H112 is the more ductile: elongation 25% versus 8% for 1070-H14, and 1070-H14 is harder (30 HB vs 22 HB). 1070-H112 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 1070-H14 machines more easily (fair vs poor).
1070-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1070-H14Choose it when strength drives the design, or when the part is machined in volume.
1070-H112 vs 1070-H14: 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.
