Aluminum 2017A vs 2030

Aluminum · grade comparison

Aluminum 2017A and 2030 are both aluminum grades, both high strength al. 2030 is the stronger of the two: yield strength 285 MPa (41.3 ksi) against 260 MPa (37.7 ksi) for 2017A, about 10% more. In exchange, 2017A is the more ductile: elongation 14% versus 12% for 2030, and 2017A is harder (110 HB vs 100 HB). 2017A runs hotter in service (120°C vs 100°C continuous). On the shop floor, 2030 machines more easily (excellent vs very good).

2017AChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

2030Choose it when strength drives the design, or when the part is machined in volume.

2017A vs 2030 — frequently asked

Is 2030 stronger than 2017A?

Yes. 2030 has a typical yield strength of 285 MPa (41.3 ksi) against 260 MPa (37.7 ksi) for 2017A — about 10% more. Tensile strength is 400 MPa (58 ksi) vs 410 MPa (59.5 ksi).

Which is cheaper, 2017A or 2030?

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 2030?

2030. Its machinability rates excellent (92/100) against very good (75/100) for 2017A; for welding the order is 2017A first (poor, 20/100) then 2030 (not recommended, 12/100).
