Aluminum 6010-O vs 6010-T6

Aluminum · 6010 temper comparison

6010-O and 6010-T6 are two conditions of the same aluminum grade, 6010: O (annealed) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. 6010-T6 is the stronger of the two: yield strength 310 MPa (45 ksi) against 70 MPa (10.2 ksi) for 6010-O, about 4.4 times as much; tensile strength follows at 350 MPa (50.8 ksi) vs 140 MPa (20.3 ksi). In exchange, 6010-O is the more ductile: elongation 28% versus 12% for 6010-T6, and 6010-T6 is harder (105 HB vs 40 HB). 6010-T6 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 6010-T6 machines more easily (very good vs fair).

6010-OChoose it when the part is bent, formed or impact-loaded.

6010-T6Choose it when strength drives the design, or when the part sees heat.

6010-O vs 6010-T6 — frequently asked

Is 6010-T6 stronger than 6010-O?

Yes. 6010-T6 has a typical yield strength of 310 MPa (45 ksi) against 70 MPa (10.2 ksi) for 6010-O — about 4.4 times as much. Tensile strength is 350 MPa (50.8 ksi) vs 140 MPa (20.3 ksi).

Which condition does FabDigit quote by default, O or T6?

Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.

Which is easier to machine, 6010-O or 6010-T6?

6010-T6. Its machinability rates very good (72/100) against fair (45/100) for 6010-O; for welding the order is 6010-O first (good, 60/100) then 6010-T6 (good, 55/100).
