Aluminum 5954-H112 vs 5954-H34
Aluminum · 5954 temper comparison
5954-H112 and 5954-H34 are two conditions of the same aluminum grade, 5954: H112 (strain hardened from hot working only) versus H34 (strain hardened and stabilized, half hard). The chemistry is identical, so every difference below comes from the condition. 5954-H34 is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 115 MPa (16.7 ksi) for 5954-H112, about 100% more; tensile strength follows at 290 MPa (42.1 ksi) vs 240 MPa (34.8 ksi). In exchange, 5954-H112 is the more ductile: elongation 20% versus 13% for 5954-H34, and 5954-H34 is harder (73 HB vs 58 HB). On the shop floor, 5954-H34 machines more easily (fair vs poor).
5954-H112Choose it when the part is bent, formed or impact-loaded.
5954-H34Choose it when strength drives the design, or when the part is machined in volume.
5954-H112 vs 5954-H34: 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.
