Aluminum 2017A vs 2A06
Aluminum · grade comparison
Aluminum 2017A and 2A06 are both aluminum grades. 2A06 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 260 MPa (37.7 ksi) for 2017A, about 23% more; tensile strength follows at 460 MPa (66.7 ksi) vs 410 MPa (59.5 ksi). In exchange, 2017A is the more ductile: elongation 14% versus 12% for 2A06, and 2A06 is harder (120 HB vs 110 HB). 2A06 runs hotter in service (150°C vs 120°C continuous) and 2017A conducts electricity better (34 % IACS vs 30 % IACS).
2017AChoose it when the part is bent, formed or impact-loaded.
2A06Choose it when strength drives the design, or when the part sees heat.
2017A vs 2A06: 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 2A06 — frequently asked
Is 2A06 stronger than 2017A?
Yes. 2A06 has a typical yield strength of 320 MPa (46.4 ksi) against 260 MPa (37.7 ksi) for 2017A — about 23% more. Tensile strength is 460 MPa (66.7 ksi) vs 410 MPa (59.5 ksi).
Which is cheaper, 2017A or 2A06?
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 2A06?
2017A. Its machinability rates very good (75/100) against good (68/100) for 2A06.
