Aluminum 6025-H32 vs 6025-T5
Aluminum · 6025 temper comparison
6025-H32 and 6025-T5 are two conditions of the same aluminum grade, 6025: H32 (strain hardened and stabilized, quarter hard) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. 6025-T5 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 205 MPa (29.7 ksi) for 6025-H32, about 20% more; tensile strength follows at 290 MPa (42.1 ksi) vs 260 MPa (37.7 ksi). In exchange, 6025-H32 is the more ductile: elongation 12% versus 10% for 6025-T5, and 6025-T5 is harder (85 HB vs 72 HB). 6025-T5 runs hotter in service (150°C vs 120°C continuous) and 6025-T5 conducts electricity better (38 % IACS vs 34 % IACS). On the shop floor, 6025-T5 machines more easily (good vs fair).
6025-H32Choose it when the part is bent, formed or impact-loaded.
6025-T5Choose it when strength drives the design, or when the part sees heat.
6025-H32 vs 6025-T5: 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.
