Aluminum EN AC-46000 F-D vs EN AC-46000-T6
Aluminum · EN AC-46000 temper comparison
EN AC-46000 F-D and EN AC-46000-T6 are two conditions of the same aluminum grade, EN AC-46000: F-D (f) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. EN AC-46000-T6 is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 155 MPa (22.5 ksi) for EN AC-46000 F-D, about 55% more; tensile strength follows at 300 MPa (43.5 ksi) vs 270 MPa (39.2 ksi). In exchange, EN AC-46000 F-D is the more ductile: elongation 1.5% versus 1% for EN AC-46000-T6, and EN AC-46000-T6 is harder (110 HB vs 85 HB). EN AC-46000-T6 runs hotter in service (170°C vs 150°C continuous) and EN AC-46000-T6 conducts heat better (120 W/m·K vs 105 W/m·K).
EN AC-46000 F-DChoose it when the part is bent, formed or impact-loaded.
EN AC-46000-T6Choose it when strength drives the design, or when the part sees heat.
EN AC-46000 F-D vs EN AC-46000-T6: 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-46000 F-D vs EN AC-46000-T6 — frequently asked
Is EN AC-46000-T6 stronger than EN AC-46000 F-D?
Yes. EN AC-46000-T6 has a typical yield strength of 240 MPa (34.8 ksi) against 155 MPa (22.5 ksi) for EN AC-46000 F-D — about 55% more. Tensile strength is 300 MPa (43.5 ksi) vs 270 MPa (39.2 ksi).
Which condition does FabDigit quote by default, F-D or T6?
F-D is the default EN AC-46000 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.
When should I choose EN AC-46000 F-D over EN AC-46000-T6?
Pick EN AC-46000 F-D when the part is bent, formed or impact-loaded. Pick EN AC-46000-T6 when strength drives the design, or when the part sees heat.
