Aluminum EN AC-45500-F vs EN AC-45500-T7
Aluminum · EN AC-45500 temper comparison
EN AC-45500-F and EN AC-45500-T7 are two conditions of the same aluminum grade, EN AC-45500: F (as fabricated) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. EN AC-45500-T7 is the stronger of the two: yield strength 210 MPa (30.5 ksi) against 100 MPa (14.5 ksi) for EN AC-45500-F, about 110% more; tensile strength follows at 260 MPa (37.7 ksi) vs 180 MPa (26.1 ksi). EN AC-45500-T7 is the more ductile: elongation 5% versus 3% for EN AC-45500-F, and EN AC-45500-T7 is harder (85 HB vs 60 HB). EN AC-45500-T7 runs hotter in service (200°C vs 150°C continuous).

EN AC-45500-F vs EN AC-45500-T7: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

EN AC-45500-F vs EN AC-45500-T7 — frequently asked
Is EN AC-45500-T7 stronger than EN AC-45500-F?
Yes. EN AC-45500-T7 has a typical yield strength of 210 MPa (30.5 ksi) against 100 MPa (14.5 ksi) for EN AC-45500-F — about 110% more. Tensile strength is 260 MPa (37.7 ksi) vs 180 MPa (26.1 ksi).
Which condition does FabDigit quote by default, F or T7?
T6 is the default EN AC-45500 condition in the FabDigit quote flow (neither F nor T7). 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, EN AC-45500-F or EN AC-45500-T7?
EN AC-45500-T7, by a small margin. Both rate good for machinability — 64/100 against 55/100 for EN AC-45500-F; for welding the order is EN AC-45500-T7 first (good, 55/100) then EN AC-45500-F (fair, 50/100).
