Aluminum 6005 vs 6011
Aluminum · grade comparison
Aluminum 6005 and 6011 are both aluminum grades, both multipurpose al. 6011 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 245 MPa (35.5 ksi) for 6005, about 35% more; tensile strength follows at 380 MPa (55.1 ksi) vs 270 MPa (39.2 ksi). 6011 is harder — 110 HB against 85 HB for 6005 — which matters for wear surfaces and threads. 6005 conducts heat better (188 W/m·K vs 165 W/m·K). On the shop floor, 6011 machines more easily (very good vs good), 6005 welds better (very good vs fair), and 6011 sits in a lower cost tier (budget, $) than 6005 (standard, $$).
6005Choose it when it will be welded.
6011Choose it when strength drives the design, or when surface hardness matters.
6005 vs 6011: 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.

6005 vs 6011 — frequently asked
Is 6011 stronger than 6005?
Yes. 6011 has a typical yield strength of 330 MPa (47.9 ksi) against 245 MPa (35.5 ksi) for 6005 — about 35% more. Tensile strength is 380 MPa (55.1 ksi) vs 270 MPa (39.2 ksi).
Which is cheaper, 6005 or 6011?
6011 is the lower-cost material: it sits in the budget tier ($) while 6005 is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 6005 or 6011?
6011. Its machinability rates very good (82/100) against good (55/100) for 6005; for welding the order is 6005 first (very good, 80/100) then 6011 (fair, 45/100).
