Aluminum 8006 vs Sintered 6061
Aluminum · grade comparison
Aluminum 8006 and Sintered 6061 are both aluminum grades. Sintered 6061 is the stronger of the two: yield strength 193 MPa (28 ksi) against 130 MPa (18.9 ksi) for 8006, about 48% more; tensile strength follows at 200 MPa (29 ksi) vs 155 MPa (22.5 ksi). In exchange, 8006 is the more ductile: elongation 10% versus 1% for Sintered 6061, and Sintered 6061 is harder (70 HB vs 45 HB). Sintered 6061 is lighter (2.55 g/cm³ vs 2.71 g/cm³ for 8006) and 8006 is stiffer (69 GPa vs 60 GPa). On the shop floor, Sintered 6061 machines more easily (very good vs fair), 8006 welds better (very good vs poor), and 8006 sits in a lower cost tier (budget, $) than Sintered 6061 (high, $$$$).
8006Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
Sintered 6061Choose it when strength drives the design, or when weight is the constraint.
8006 vs Sintered 6061: 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.
