Aluminum 6005 vs 6111
Aluminum · grade comparison
Aluminum 6005 and 6111 are both aluminum grades. 6005 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 160 MPa (23.2 ksi) for 6111, about 53% more. In exchange, 6111 is the more ductile: elongation 26% versus 11% for 6005, and 6005 is harder (85 HB vs 78 HB). 6005 runs hotter in service (150°C vs 120°C continuous) and 6005 conducts heat better (188 W/m·K vs 165 W/m·K). On the shop floor, 6111 machines more easily (65 vs 55 out of 100) and 6005 welds better (very good vs good).
6005Choose it when strength drives the design, or when the part sees heat.
6111Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
6005 vs 6111: 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 6111 — frequently asked
Is 6005 stronger than 6111?
Yes. 6005 has a typical yield strength of 245 MPa (35.5 ksi) against 160 MPa (23.2 ksi) for 6111 — about 53% more. Tensile strength is 270 MPa (39.2 ksi) vs 295 MPa (42.8 ksi).
Which is cheaper, 6005 or 6111?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 6005 or 6111?
6111, by a small margin. Both rate good for machinability — 65/100 against 55/100 for 6005; for welding the order is 6005 first (very good, 80/100) then 6111 (good, 55/100).
