Aluminum 6262-T6 vs 6262-T9
Aluminum · 6262 temper comparison
6262-T6 and 6262-T9 are two conditions of the same aluminum grade, 6262: T6 (solution heat treated and artificially aged) versus T9 (solution heat treated, artificially aged and cold worked). The chemistry is identical, so every difference below comes from the condition. 6262-T9 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 275 MPa (39.9 ksi) for 6262-T6, about 38% more; tensile strength follows at 400 MPa (58 ksi) vs 310 MPa (45 ksi). In exchange, 6262-T6 is the more ductile: elongation 12% versus 10% for 6262-T9, and 6262-T9 is harder (120 HB vs 95 HB).
6262-T6Choose it when the part is bent, formed or impact-loaded.
6262-T9Choose it when strength drives the design.
6262-T6 vs 6262-T9: 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.
