Aluminum 6061-T6 vs 6082-T6
Aluminum · grade comparison
Aluminum 6061-T6 and 6082-T6 are both aluminum grades, compared here in the T6 condition. Both yield at about 276 MPa — strength does not separate them. 6061-T6 is the more ductile: elongation 12% versus 10% for 6082-T6, and 6061-T6 is harder (107 HV vs 100 HV). 6061-T6 runs hotter in service (170°C vs 150°C continuous). On the shop floor, 6061-T6 welds better (excellent vs very good) and 6061-T6 sits in a lower cost tier (budget, $) than 6082-T6 (standard, $$).

6061-T6 vs 6082-T6: 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.
