Aluminum 2007 vs 2014
Aluminum · grade comparison
Aluminum 2007 and 2014 are both aluminum grades. 2014 is the stronger of the two: yield strength 414 MPa (60 ksi) against 300 MPa (43.5 ksi) for 2007, about 38% more; tensile strength follows at 483 MPa (70.1 ksi) vs 390 MPa (56.6 ksi). 2014 is the more ductile: elongation 13% versus 10% for 2007, and 2014 is harder (135 HB vs 115 HB). 2014 runs hotter in service (150°C vs 120°C continuous) and 2014 conducts heat better (155 W/m·K vs 135 W/m·K). On the shop floor, 2007 machines more easily (excellent vs very good) and 2014 welds better (25 vs 15 out of 100).
2007Choose it when the part is machined in volume.
2014Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
2007 vs 2014: 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.

2007 vs 2014 — frequently asked
Is 2014 stronger than 2007?
Yes. 2014 has a typical yield strength of 414 MPa (60 ksi) against 300 MPa (43.5 ksi) for 2007 — about 38% more. Tensile strength is 483 MPa (70.1 ksi) vs 390 MPa (56.6 ksi).
Which is cheaper, 2007 or 2014?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 2007 or 2014?
2007. Its machinability rates excellent (95/100) against very good (78/100) for 2014; for welding the order is 2014 first (poor, 25/100) then 2007 (poor, 15/100).
