Aluminum EN AC-45000-F vs EN AC-45000-T5

Aluminum · EN AC-45000 temper comparison

EN AC-45000-F and EN AC-45000-T5 are two conditions of the same aluminum grade, EN AC-45000: F (as fabricated) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. EN AC-45000-T5 is the stronger of the two: yield strength 140 MPa (20.3 ksi) against 100 MPa (14.5 ksi) for EN AC-45000-F, about 40% more; tensile strength follows at 205 MPa (29.7 ksi) vs 170 MPa (24.7 ksi). EN AC-45000-T5 is harder — 80 HB against 70 HB for EN AC-45000-F — which matters for wear surfaces and threads. EN AC-45000-T5 runs hotter in service (200°C vs 150°C continuous).

EN AC-45000-T5Choose it when strength drives the design, or when surface hardness matters.
