Aluminum EN AC-71000-F vs EN AC-71000-T1

Aluminum · EN AC-71000 temper comparison

EN AC-71000-F and EN AC-71000-T1 are two conditions of the same aluminum grade, EN AC-71000: F (as fabricated) versus T1 (cooled from hot working and naturally aged). The chemistry is identical, so every difference below comes from the condition. EN AC-71000-T1 is the stronger of the two: yield strength 155 MPa (22.5 ksi) against 145 MPa (21 ksi) for EN AC-71000-F, about 7% more. In exchange, EN AC-71000-F is the more ductile: elongation 4% versus 2.5% for EN AC-71000-T1, and EN AC-71000-T1 is harder (85 HB vs 62 HB).

EN AC-71000-FChoose it when the part is bent, formed or impact-loaded.

EN AC-71000-T1Choose it when strength drives the design.
