Aluminum EN AC-46200-T5 vs EN AC-46200-T7
Aluminum · EN AC-46200 temper comparison
EN AC-46200-T5 and EN AC-46200-T7 are two conditions of the same aluminum grade, EN AC-46200: T5 (cooled from hot working and artificially aged) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. EN AC-46200-T5 is the stronger of the two: yield strength 175 MPa (25.4 ksi) against 155 MPa (22.5 ksi) for EN AC-46200-T7, about 13% more. In exchange, EN AC-46200-T7 is the more ductile: elongation 3% versus 1.5% for EN AC-46200-T5, and EN AC-46200-T5 is harder (85 HB vs 80 HB). EN AC-46200-T7 runs hotter in service (200°C vs 175°C continuous).
EN AC-46200-T5Choose it when strength drives the design.
EN AC-46200-T7Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
EN AC-46200-T5 vs EN AC-46200-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-46200-T5 vs EN AC-46200-T7 — frequently asked
Is EN AC-46200-T5 stronger than EN AC-46200-T7?
Yes. EN AC-46200-T5 has a typical yield strength of 175 MPa (25.4 ksi) against 155 MPa (22.5 ksi) for EN AC-46200-T7 — about 13% more. Tensile strength is 215 MPa (31.2 ksi) vs 230 MPa (33.4 ksi).
Which condition does FabDigit quote by default, T5 or T7?
F-K is the default EN AC-46200 condition in the FabDigit quote flow (neither T5 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.
When should I choose EN AC-46200-T5 over EN AC-46200-T7?
Pick EN AC-46200-T5 when strength drives the design. Pick EN AC-46200-T7 when the part is bent, formed or impact-loaded, or when the part sees heat.
