Aluminum 6060 vs 6253

Aluminum · grade comparison

Aluminum 6060 and 6253 are both aluminum grades. 6253 is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 170 MPa (24.7 ksi) for 6060, about 29% more; tensile strength follows at 255 MPa (37 ksi) vs 215 MPa (31.2 ksi). 6253 is harder — 80 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, 6253 machines more easily (65 vs 55 out of 100), 6060 welds better (excellent vs good), and 6060 forms better (good vs fair).

6060Choose it when it will be welded, or when cost is the deciding factor.

6253Choose it when strength drives the design, or when surface hardness matters.

6060 vs 6253 — frequently asked

Is 6253 stronger than 6060?

Yes. 6253 has a typical yield strength of 220 MPa (31.9 ksi) against 170 MPa (24.7 ksi) for 6060 — about 29% more. Tensile strength is 255 MPa (37 ksi) vs 215 MPa (31.2 ksi).

Which is cheaper, 6060 or 6253?

6060 is the lower-cost material: it sits in the budget tier ($) while 6253 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 6253?

6253, 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 6253 (good, 65/100).
