Aluminum EN AC-46300-T5 vs EN AC-46300-T7

Aluminum · EN AC-46300 temper comparison

EN AC-46300-T5 and EN AC-46300-T7 are two conditions of the same aluminum grade, EN AC-46300: 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-46300-T7 is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 200 MPa (29 ksi) for EN AC-46300-T5, about 15% more; tensile strength follows at 285 MPa (41.3 ksi) vs 270 MPa (39.2 ksi). EN AC-46300-T7 is the more ductile: elongation 1.5% versus 1% for EN AC-46300-T5. EN AC-46300-T7 runs hotter in service (200°C vs 175°C continuous).

EN AC-46300-T7Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

EN AC-46300-T5 vs EN AC-46300-T7 — frequently asked

Is EN AC-46300-T7 stronger than EN AC-46300-T5?

Yes. EN AC-46300-T7 has a typical yield strength of 230 MPa (33.4 ksi) against 200 MPa (29 ksi) for EN AC-46300-T5 — about 15% more. Tensile strength is 285 MPa (41.3 ksi) vs 270 MPa (39.2 ksi).

Which condition does FabDigit quote by default, T5 or T7?

F is the default EN AC-46300 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-46300-T5 over EN AC-46300-T7?

Pick EN AC-46300-T7 when strength drives the design, or when the part is bent, formed or impact-loaded.
