Aluminum 2030 vs 2A17

Aluminum · grade comparison

Aluminum 2030 and 2A17 are both aluminum grades. 2A17 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 285 MPa (41.3 ksi) for 2030, about 12% more; tensile strength follows at 440 MPa (63.8 ksi) vs 400 MPa (58 ksi). In exchange, 2030 is the more ductile: elongation 12% versus 9% for 2A17, and 2A17 is harder (120 HB vs 100 HB). 2A17 runs hotter in service (250°C vs 100°C continuous). On the shop floor, 2030 machines more easily (excellent vs very good), 2A17 welds better (good vs not recommended), and 2030 sits in a lower cost tier (premium, $$$) than 2A17 (high, $$$$).

2030Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

2A17Choose it when strength drives the design, or when the part sees heat.

2030 vs 2A17 — frequently asked

Is 2A17 stronger than 2030?

Yes. 2A17 has a typical yield strength of 320 MPa (46.4 ksi) against 285 MPa (41.3 ksi) for 2030 — about 12% more. Tensile strength is 440 MPa (63.8 ksi) vs 400 MPa (58 ksi).

Which is cheaper, 2030 or 2A17?

2030 is the lower-cost material: it sits in the premium tier ($$$) while 2A17 is high ($$$$). 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, 2030 or 2A17?

2030. Its machinability rates excellent (92/100) against very good (72/100) for 2A17; for welding the order is 2A17 first (good, 58/100) then 2030 (not recommended, 12/100).
