Aluminum 2014A vs 2017A
Aluminum · grade comparison
Aluminum 2014A and 2017A are both aluminum grades. 2014A is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 260 MPa (37.7 ksi) for 2017A, about 60% more; tensile strength follows at 470 MPa (68.2 ksi) vs 410 MPa (59.5 ksi). In exchange, 2017A is the more ductile: elongation 14% versus 9% for 2014A, and 2014A is harder (135 HB vs 110 HB). 2014A runs hotter in service (150°C vs 120°C continuous) and 2014A conducts heat better (155 W/m·K vs 134 W/m·K).
2014AChoose it when strength drives the design, or when the part sees heat.
2017AChoose it when the part is bent, formed or impact-loaded.
2014A vs 2017A: 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.

2014A vs 2017A — frequently asked
Is 2014A stronger than 2017A?
Yes. 2014A has a typical yield strength of 415 MPa (60.2 ksi) against 260 MPa (37.7 ksi) for 2017A — about 60% more. Tensile strength is 470 MPa (68.2 ksi) vs 410 MPa (59.5 ksi).
Which is cheaper, 2014A or 2017A?
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, 2014A or 2017A?
2014A, by a small margin. Both rate very good for machinability — 80/100 against 75/100 for 2017A; for welding the order is 2014A first (poor, 25/100) then 2017A (poor, 20/100).
