Aluminum EN AC-48100-F vs EN AC-48100-T6
Aluminum · EN AC-48100 temper comparison
EN AC-48100-F and EN AC-48100-T6 are two conditions of the same aluminum grade, EN AC-48100: 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-48100-T6 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 180 MPa (26.1 ksi) for EN AC-48100-F, about 67% more; tensile strength follows at 310 MPa (45 ksi) vs 190 MPa (27.6 ksi). EN AC-48100-T6 is harder — 145 HB against 105 HB for EN AC-48100-F — which matters for wear surfaces and threads. EN AC-48100-F runs hotter in service (250°C vs 175°C continuous). On the shop floor, EN AC-48100-F welds better (fair vs poor).
EN AC-48100-FChoose it when the part sees heat, or when it will be welded.
EN AC-48100-T6Choose it when strength drives the design, or when surface hardness matters.
EN AC-48100-F vs EN AC-48100-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.
