Aluminum 5025-H12 vs 5025-H16
Aluminum · 5025 temper comparison
5025-H12 and 5025-H16 are two conditions of the same aluminum grade, 5025: H12 (strain hardened, quarter hard) versus H16 (strain hardened, three-quarter hard). The chemistry is identical, so every difference below comes from the condition. 5025-H16 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 165 MPa (23.9 ksi) for 5025-H12, about 24% more; tensile strength follows at 230 MPa (33.4 ksi) vs 190 MPa (27.6 ksi). In exchange, 5025-H12 is the more ductile: elongation 9% versus 5% for 5025-H16, and 5025-H16 is harder (65 HB vs 50 HB). 5025-H12 runs hotter in service (120°C vs 110°C continuous).
5025-H12Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5025-H16Choose it when strength drives the design.
5025-H12 vs 5025-H16: 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.
