Aluminum EN AC-45100-F vs EN AC-45100-T6

Aluminum · EN AC-45100 temper comparison

EN AC-45100-F and EN AC-45100-T6 are two conditions of the same aluminum grade, EN AC-45100: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. EN AC-45100-T6 is the stronger of the two: yield strength 215 MPa (31.2 ksi) against 105 MPa (15.2 ksi) for EN AC-45100-F, about 105% more; tensile strength follows at 260 MPa (37.7 ksi) vs 175 MPa (25.4 ksi). In exchange, EN AC-45100-F is the more ductile: elongation 1.5% versus 1.2% for EN AC-45100-T6, and EN AC-45100-T6 is harder (100 HB vs 65 HB).
