Aluminum 2017A vs 2N01
Aluminum · grade comparison
Aluminum 2017A and 2N01 are both aluminum grades. 2N01 is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 260 MPa (37.7 ksi) for 2017A, about 8% more. In exchange, 2017A is the more ductile: elongation 14% versus 12% for 2N01, and 2N01 is harder (125 HV vs 118 HV). 2N01 runs hotter in service (200°C vs 120°C continuous) and 2N01 conducts heat better (150 W/m·K vs 134 W/m·K). On the shop floor, 2017A sits in a lower cost tier (premium, $$$) than 2N01 (high, $$$$).
2017AChoose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
2N01Choose it when strength drives the design, or when the part sees heat.
2017A vs 2N01: 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 2N01 — frequently asked
Is 2N01 stronger than 2017A?
Yes. 2N01 has a typical yield strength of 280 MPa (40.6 ksi) against 260 MPa (37.7 ksi) for 2017A — about 8% more. Tensile strength is 400 MPa (58 ksi) vs 410 MPa (59.5 ksi).
Which is cheaper, 2017A or 2N01?
2017A is the lower-cost material: it sits in the premium tier ($$$) while 2N01 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
When should I choose 2017A over 2N01?
Pick 2017A when the part is bent, formed or impact-loaded, or when cost is the deciding factor. Pick 2N01 when strength drives the design, or when the part sees heat.
