Aluminum 2017 vs 2214
Aluminum · grade comparison
Aluminum 2017 and 2214 are both aluminum grades, both high strength al. 2214 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 276 MPa (40 ksi) for 2017, about 50% more; tensile strength follows at 470 MPa (68.2 ksi) vs 427 MPa (61.9 ksi). In exchange, 2017 is the more ductile: elongation 22% versus 9% for 2214, and 2214 is harder (135 HB vs 105 HB). 2214 runs hotter in service (150°C vs 120°C continuous) and 2214 conducts heat better (155 W/m·K vs 134 W/m·K).
2017Choose it when the part is bent, formed or impact-loaded.
2214Choose it when strength drives the design, or when the part sees heat.
2017 vs 2214: 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.

2017 vs 2214 — frequently asked
Is 2214 stronger than 2017?
Yes. 2214 has a typical yield strength of 415 MPa (60.2 ksi) against 276 MPa (40 ksi) for 2017 — about 50% more. Tensile strength is 470 MPa (68.2 ksi) vs 427 MPa (61.9 ksi).
Which is cheaper, 2017 or 2214?
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 welds better, 2017 or 2214?
2214. Its weldability rates poor (25/100) against poor (20/100) for 2017.
