Aluminum A201.0-F vs A201.0-T6

Aluminum · A201.0 temper comparison

A201.0-F and A201.0-T6 are two conditions of the same aluminum grade, A201.0: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. A201.0-T6 is the stronger of the two: yield strength 435 MPa (63.1 ksi) against 125 MPa (18.1 ksi) for A201.0-F, about 3.5 times as much; tensile strength follows at 483 MPa (70.1 ksi) vs 200 MPa (29 ksi). A201.0-T6 is the more ductile: elongation 5% versus 3% for A201.0-F, and A201.0-T6 is harder (140 HB vs 65 HB). On the shop floor, A201.0-T6 machines more easily (very good vs good).

A201.0-T6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

A201.0-F vs A201.0-T6 — frequently asked

Is A201.0-T6 stronger than A201.0-F?

Yes. A201.0-T6 has a typical yield strength of 435 MPa (63.1 ksi) against 125 MPa (18.1 ksi) for A201.0-F — about 3.5 times as much. Tensile strength is 483 MPa (70.1 ksi) vs 200 MPa (29 ksi).

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

T7 is the default A201.0 condition in the FabDigit quote flow (neither F nor T6). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, A201.0-F or A201.0-T6?

A201.0-T6. Its machinability rates very good (72/100) against good (60/100) for A201.0-F; for welding the order is A201.0-T6 first (fair, 40/100) then A201.0-F (fair, 35/100).
