Aluminum 2020 vs 2030

Aluminum · grade comparison

Aluminum 2020 and 2030 are both aluminum grades. 2020 is the stronger of the two: yield strength 530 MPa (76.9 ksi) against 285 MPa (41.3 ksi) for 2030, about 86% more; tensile strength follows at 580 MPa (84.1 ksi) vs 400 MPa (58 ksi). In exchange, 2030 is the more ductile: elongation 12% versus 4% for 2020, and 2020 is harder (150 HB vs 100 HB). 2020 runs hotter in service (150°C vs 100°C continuous). On the shop floor, 2030 machines more easily (excellent vs good) and 2030 sits in a lower cost tier (premium, $$$) than 2020 (high, $$$$).

2020Choose it when strength drives the design, or when the part sees heat.

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

2020 vs 2030 — frequently asked

Is 2020 stronger than 2030?

Yes. 2020 has a typical yield strength of 530 MPa (76.9 ksi) against 285 MPa (41.3 ksi) for 2030 — about 86% more. Tensile strength is 580 MPa (84.1 ksi) vs 400 MPa (58 ksi).

Which is cheaper, 2020 or 2030?

2030 is the lower-cost material: it sits in the premium tier ($$$) while 2020 is high ($$$$). 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, 2020 or 2030?

2030. Its machinability rates excellent (92/100) against good (62/100) for 2020.
