Aluminum 2017A vs 2036
Aluminum · grade comparison
Aluminum 2017A and 2036 are both aluminum grades. 2017A is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 195 MPa (28.3 ksi) for 2036, about 33% more; tensile strength follows at 410 MPa (59.5 ksi) vs 340 MPa (49.3 ksi). In exchange, 2036 is the more ductile: elongation 24% versus 14% for 2017A, and 2017A is harder (110 HB vs 80 HB). 2036 conducts heat better (159 W/m·K vs 134 W/m·K). On the shop floor, 2017A machines more easily (very good vs good) and 2036 welds better (fair vs poor).
2017AChoose it when strength drives the design, or when the part is machined in volume.
2036Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
2017A vs 2036: 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.

2017A vs 2036 — frequently asked
Is 2017A stronger than 2036?
Yes. 2017A has a typical yield strength of 260 MPa (37.7 ksi) against 195 MPa (28.3 ksi) for 2036 — about 33% more. Tensile strength is 410 MPa (59.5 ksi) vs 340 MPa (49.3 ksi).
Which is cheaper, 2017A or 2036?
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, 2017A or 2036?
2017A. Its machinability rates very good (75/100) against good (65/100) for 2036; for welding the order is 2036 first (fair, 35/100) then 2017A (poor, 20/100).
