Aluminum EN AC-48000-F vs EN AC-48000-T6
Aluminum · EN AC-48000 temper comparison
EN AC-48000-F and EN AC-48000-T6 are two conditions of the same aluminum grade, EN AC-48000: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. EN AC-48000-T6 is the stronger of the two: yield strength 255 MPa (37 ksi) against 130 MPa (18.9 ksi) for EN AC-48000-F, about 96% more; tensile strength follows at 295 MPa (42.8 ksi) vs 180 MPa (26.1 ksi). In exchange, EN AC-48000-F is the more ductile: elongation 1.5% versus 1% for EN AC-48000-T6, and EN AC-48000-T6 is harder (115 HB vs 85 HB). EN AC-48000-T6 runs hotter in service (250°C vs 180°C continuous) and EN AC-48000-T6 conducts electricity better (33 % IACS vs 29 % IACS). On the shop floor, EN AC-48000-F machines more easily (good vs fair).
EN AC-48000-FChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
EN AC-48000-T6Choose it when strength drives the design, or when the part sees heat.
EN AC-48000-F vs EN AC-48000-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.
