Aluminum 5754-H112 vs 5754-H32
Aluminum · 5754 temper comparison
5754-H112 and 5754-H32 are two conditions of the same aluminum grade, 5754: H112 (strain hardened from hot working only) versus H32 (strain hardened and stabilized, quarter hard). The chemistry is identical, so every difference below comes from the condition. 5754-H32 is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 95 MPa (13.8 ksi) for 5754-H112, about 58% more; tensile strength follows at 245 MPa (35.5 ksi) vs 200 MPa (29 ksi). In exchange, 5754-H112 is the more ductile: elongation 16% versus 13% for 5754-H32, and 5754-H32 is harder (66 HB vs 52 HB). 5754-H112 runs hotter in service (80°C vs 65°C continuous). On the shop floor, 5754-H32 machines more easily (45 vs 35 out of 100).
5754-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5754-H32Choose it when strength drives the design, or when the part is machined in volume.
5754-H112 vs 5754-H32: 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.
