Aluminum EN AC-48100-T5 vs EN AC-48100-T6

Aluminum · EN AC-48100 temper comparison

EN AC-48100-T5 and EN AC-48100-T6 are two conditions of the same aluminum grade, EN AC-48100: T5 (cooled from hot working and artificially aged) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. EN AC-48100-T6 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 195 MPa (28.3 ksi) for EN AC-48100-T5, about 54% more; tensile strength follows at 310 MPa (45 ksi) vs 210 MPa (30.5 ksi). EN AC-48100-T6 is the more ductile: elongation 0.8% versus 0.7% for EN AC-48100-T5, and EN AC-48100-T6 is harder (145 HB vs 115 HB). EN AC-48100-T5 runs hotter in service (200°C vs 175°C continuous). On the shop floor, EN AC-48100-T5 welds better (fair vs poor).

EN AC-48100-T5Choose it when the part sees heat, or when it will be welded.

EN AC-48100-T6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
