Aluminum 6005 vs 6014
Aluminum · grade comparison
Aluminum 6005 and 6014 are both aluminum grades. 6005 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 120 MPa (17.4 ksi) for 6014, about 104% more; tensile strength follows at 270 MPa (39.2 ksi) vs 220 MPa (31.9 ksi). In exchange, 6014 is the more ductile: elongation 27% versus 11% for 6005, and 6005 is harder (85 HB vs 60 HB). 6005 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 6005 sits in a lower cost tier (standard, $$) than 6014 (premium, $$$).
6005Choose it when strength drives the design, or when the part sees heat.
6014Choose it when the part is bent, formed or impact-loaded.
6005 vs 6014: 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 6014 — frequently asked
Is 6005 stronger than 6014?
Yes. 6005 has a typical yield strength of 245 MPa (35.5 ksi) against 120 MPa (17.4 ksi) for 6014 — about 104% more. Tensile strength is 270 MPa (39.2 ksi) vs 220 MPa (31.9 ksi).
Which is cheaper, 6005 or 6014?
6005 is the lower-cost material: it sits in the standard tier ($$) while 6014 is premium ($$$). 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 6014?
6005. Its machinability rates good (55/100) against fair (50/100) for 6014; for welding the order is 6005 first (very good, 80/100) then 6014 (very good, 75/100).
