Aluminum 2011 vs 6020

Aluminum · grade comparison

Aluminum 2011 and 6020 are both aluminum grades, both machining-friendly al. 2011 is the stronger of the two: tensile strength 379 MPa (55 ksi) against 330 MPa (47.9 ksi) for 6020, about 15% more. 2011 is the more ductile: elongation 15% versus 11% for 6020, and 6020 is harder (100 HB vs 95 HB). 6020 is lighter (2.7 g/cm³ vs 2.83 g/cm³ for 2011) and 6020 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 6020 welds better (poor vs not recommended) and 6020 sits in a lower cost tier (standard, $$) than 2011 (premium, $$$).

2011Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

6020Choose it when weight is the constraint, or when the part sees heat.

2011 vs 6020 — frequently asked

Is 2011 stronger than 6020?

Yes. 2011 has a typical tensile strength of 379 MPa (55 ksi) against 330 MPa (47.9 ksi) for 6020 — about 15% more.

Which is cheaper, 2011 or 6020?

6020 is the lower-cost material: it sits in the standard tier ($$) while 2011 is premium ($$$). 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, 2011 or 6020?

2011, by a small margin. Both rate excellent for machinability — 100/100 against 92/100 for 6020; for welding the order is 6020 first (poor, 25/100) then 2011 (not recommended, 10/100).
