Aluminum EN AC-46600-T5 vs EN AC-46600 T6-S
Aluminum · EN AC-46600 temper comparison
EN AC-46600-T5 and EN AC-46600 T6-S are two conditions of the same aluminum grade, EN AC-46600: T5 (cooled from hot working and artificially aged) versus T6-S (T6). The chemistry is identical, so every difference below comes from the condition. EN AC-46600 T6-S is the stronger of the two: yield strength 200 MPa (29 ksi) against 170 MPa (24.7 ksi) for EN AC-46600-T5, about 18% more. EN AC-46600 T6-S is harder — 90 HB against 85 HB for EN AC-46600-T5 — which matters for wear surfaces and threads. EN AC-46600-T5 runs hotter in service (175°C vs 150°C continuous).

EN AC-46600-T5 vs EN AC-46600 T6-S: 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-46600-T5 vs EN AC-46600 T6-S — frequently asked
Is EN AC-46600 T6-S stronger than EN AC-46600-T5?
Yes. EN AC-46600 T6-S has a typical yield strength of 200 MPa (29 ksi) against 170 MPa (24.7 ksi) for EN AC-46600-T5 — about 18% more. Tensile strength is 240 MPa (34.8 ksi) vs 230 MPa (33.4 ksi).
Which condition does FabDigit quote by default, T5 or T6-S?
F-D is the default EN AC-46600 condition in the FabDigit quote flow (neither T5 nor T6-S). 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 welds better, EN AC-46600-T5 or EN AC-46600 T6-S?
EN AC-46600-T5. Its weldability rates poor (30/100) against poor (25/100) for EN AC-46600 T6-S.
