Aluminum 6060 vs 6201
Aluminum · grade comparison
Aluminum 6060 and 6201 are both aluminum grades. 6201 is the stronger of the two: yield strength 310 MPa (45 ksi) against 170 MPa (24.7 ksi) for 6060, about 82% more; tensile strength follows at 330 MPa (47.9 ksi) vs 215 MPa (31.2 ksi). In exchange, 6060 is the more ductile: elongation 12% versus 4% for 6201, and 6201 is harder (100 HB vs 75 HB). 6060 runs hotter in service (150°C vs 90°C continuous). On the shop floor, 6201 machines more easily (65 vs 55 out of 100), 6060 welds better (excellent vs good), and 6060 sits in a lower cost tier (budget, $) than 6201 (standard, $$).
6060Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
6201Choose it when strength drives the design, or when the part is machined in volume.
6060 vs 6201: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

6060 vs 6201 — frequently asked
Is 6201 stronger than 6060?
Yes. 6201 has a typical yield strength of 310 MPa (45 ksi) against 170 MPa (24.7 ksi) for 6060 — about 82% more. Tensile strength is 330 MPa (47.9 ksi) vs 215 MPa (31.2 ksi).
Which is cheaper, 6060 or 6201?
6060 is the lower-cost material: it sits in the budget tier ($) while 6201 is standard ($$). 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, 6060 or 6201?
6201, by a small margin. Both rate good for machinability — 65/100 against 55/100 for 6060; for welding the order is 6060 first (excellent, 90/100) then 6201 (good, 62/100).
