Aluminum 201.0-F vs 201.0-T7

Aluminum · 201.0 temper comparison

201.0-F and 201.0-T7 are two conditions of the same aluminum grade, 201.0: F (as fabricated) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. 201.0-T7 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 110 MPa (16 ksi) for 201.0-F, about 3.8 times as much; tensile strength follows at 470 MPa (68.2 ksi) vs 190 MPa (27.6 ksi). 201.0-T7 is the more ductile: elongation 6% versus 4% for 201.0-F, and 201.0-T7 is harder (130 HB vs 65 HB). 201.0-T7 runs hotter in service (200°C vs 120°C continuous) and 201.0-F conducts heat better (135 W/m·K vs 121 W/m·K). On the shop floor, 201.0-T7 machines more easily (65 vs 55 out of 100).

201.0-T7Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

201.0-F vs 201.0-T7 — frequently asked

Is 201.0-T7 stronger than 201.0-F?

Yes. 201.0-T7 has a typical yield strength of 420 MPa (60.9 ksi) against 110 MPa (16 ksi) for 201.0-F — about 3.8 times as much. Tensile strength is 470 MPa (68.2 ksi) vs 190 MPa (27.6 ksi).

Which condition does FabDigit quote by default, F or T7?

T7 is the default 201.0 condition in the FabDigit quote flow. 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, 201.0-F or 201.0-T7?

201.0-T7, by a small margin. Both rate good for machinability — 65/100 against 55/100 for 201.0-F.
