Aluminum 2017A vs 2065

Aluminum · grade comparison

Aluminum 2017A and 2065 are both aluminum grades. 2065 is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 260 MPa (37.7 ksi) for 2017A, about 77% more; tensile strength follows at 505 MPa (73.2 ksi) vs 410 MPa (59.5 ksi). In exchange, 2017A is the more ductile: elongation 14% versus 9% for 2065, and 2065 is harder (145 HB vs 110 HB). 2065 is lighter (2.7 g/cm³ vs 2.79 g/cm³ for 2017A) and 2065 is stiffer (78 GPa vs 72.5 GPa). On the shop floor, 2017A machines more easily (very good vs good) and 2017A sits in a lower cost tier (premium, $$$) than 2065 (high, $$$$).

2017AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

2065Choose it when strength drives the design, or when weight is the constraint.

2017A vs 2065 — frequently asked

Is 2065 stronger than 2017A?

Yes. 2065 has a typical yield strength of 460 MPa (66.7 ksi) against 260 MPa (37.7 ksi) for 2017A — about 77% more. Tensile strength is 505 MPa (73.2 ksi) vs 410 MPa (59.5 ksi).

Which is cheaper, 2017A or 2065?

2017A is the lower-cost material: it sits in the premium tier ($$$) while 2065 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 2017A or 2065?

2017A. Its machinability rates very good (75/100) against good (62/100) for 2065; for welding the order is 2065 first (poor, 25/100) then 2017A (poor, 20/100).
