Aluminum 6060 vs 6A02
Aluminum · grade comparison
Aluminum 6060 and 6A02 are both aluminum grades. 6A02 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 170 MPa (24.7 ksi) for 6060, about 47% more; tensile strength follows at 320 MPa (46.4 ksi) vs 215 MPa (31.2 ksi). 6A02 is harder — 95 HB against 75 HB for 6060 — which matters for wear surfaces and threads. 6060 conducts heat better (200 W/m·K vs 165 W/m·K). On the shop floor, 6060 welds better (excellent vs very good), 6060 forms better (good vs fair), and 6060 sits in a lower cost tier (budget, $) than 6A02 (premium, $$$).
6060Choose it when it will be welded, or when cost is the deciding factor.
6A02Choose it when strength drives the design, or when surface hardness matters.
6060 vs 6A02: 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 6A02 — frequently asked
Is 6A02 stronger than 6060?
Yes. 6A02 has a typical yield strength of 250 MPa (36.3 ksi) against 170 MPa (24.7 ksi) for 6060 — about 47% more. Tensile strength is 320 MPa (46.4 ksi) vs 215 MPa (31.2 ksi).
Which is cheaper, 6060 or 6A02?
6060 is the lower-cost material: it sits in the budget tier ($) while 6A02 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, 6060 or 6A02?
6A02, by a small margin. Both rate good for machinability — 62/100 against 55/100 for 6060; for welding the order is 6060 first (excellent, 90/100) then 6A02 (very good, 72/100).
