Aluminum 6262-T6511 vs 6262-T8
Aluminum · 6262 temper comparison
6262-T6511 and 6262-T8 are two conditions of the same aluminum grade, 6262: T6511 (T6, stress relieved by stretching, minor straightening) versus T8 (solution heat treated, cold worked and artificially aged). The chemistry is identical, so every difference below comes from the condition. 6262-T8 is the stronger of the two: yield strength 365 MPa (52.9 ksi) against 275 MPa (39.9 ksi) for 6262-T6511, about 33% more; tensile strength follows at 395 MPa (57.3 ksi) vs 310 MPa (45 ksi). 6262-T8 is harder — 118 HB against 95 HB for 6262-T6511 — which matters for wear surfaces and threads. On the shop floor, 6262-T6511 forms better (fair vs poor).
6262-T8Choose it when strength drives the design, or when surface hardness matters.
6262-T6511 vs 6262-T8: 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.
