Aluminum 2A80-F vs 2A80-T6

Aluminum · 2A80 temper comparison

2A80-F and 2A80-T6 are two conditions of the same aluminum grade, 2A80: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. 2A80-T6 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 155 MPa (22.5 ksi) for 2A80-F, about 145% more; tensile strength follows at 440 MPa (63.8 ksi) vs 275 MPa (39.9 ksi). In exchange, 2A80-F is the more ductile: elongation 12% versus 8% for 2A80-T6, and 2A80-T6 is harder (125 HB vs 80 HB). 2A80-T6 runs hotter in service (200°C vs 150°C continuous). On the shop floor, 2A80-T6 machines more easily (68 vs 55 out of 100).

2A80-F vs 2A80-T6 — frequently asked

Is 2A80-T6 stronger than 2A80-F?

Yes. 2A80-T6 has a typical yield strength of 380 MPa (55.1 ksi) against 155 MPa (22.5 ksi) for 2A80-F — about 145% more. Tensile strength is 440 MPa (63.8 ksi) vs 275 MPa (39.9 ksi).

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

T6 is the default 2A80 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, 2A80-F or 2A80-T6?

2A80-T6, by a small margin. Both rate good for machinability — 68/100 against 55/100 for 2A80-F.
