Aluminum 6005 vs 6110A
Aluminum · grade comparison
Aluminum 6005 and 6110A are both aluminum grades. 6110A is the stronger of the two: yield strength 355 MPa (51.5 ksi) against 245 MPa (35.5 ksi) for 6005, about 45% more; tensile strength follows at 385 MPa (55.8 ksi) vs 270 MPa (39.2 ksi). 6110A is harder — 115 HB against 85 HB for 6005 — which matters for wear surfaces and threads. 6005 conducts heat better (188 W/m·K vs 160 W/m·K). On the shop floor, 6005 welds better (very good vs good) and 6005 sits in a lower cost tier (standard, $$) than 6110A (premium, $$$).
6005Choose it when it will be welded, or when cost is the deciding factor.
6110AChoose it when strength drives the design, or when surface hardness matters.
6005 vs 6110A: 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 6110A — frequently asked
Is 6110A stronger than 6005?
Yes. 6110A has a typical yield strength of 355 MPa (51.5 ksi) against 245 MPa (35.5 ksi) for 6005 — about 45% more. Tensile strength is 385 MPa (55.8 ksi) vs 270 MPa (39.2 ksi).
Which is cheaper, 6005 or 6110A?
6005 is the lower-cost material: it sits in the standard tier ($$) while 6110A is premium ($$$). 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 6110A?
6110A, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 6005; for welding the order is 6005 first (very good, 80/100) then 6110A (good, 65/100).
