Aluminum EN AC-51500-F vs EN AC-51500-T5

Aluminum · EN AC-51500 temper comparison

EN AC-51500-F and EN AC-51500-T5 are two conditions of the same aluminum grade, EN AC-51500: 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-51500-T5 is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 185 MPa (26.8 ksi) for EN AC-51500-F, about 24% more; tensile strength follows at 305 MPa (44.2 ksi) vs 285 MPa (41.3 ksi). In exchange, EN AC-51500-F is the more ductile: elongation 12% versus 8% for EN AC-51500-T5, and EN AC-51500-T5 is harder (95 HB vs 85 HB). EN AC-51500-T5 runs hotter in service (120°C vs 100°C continuous).

EN AC-51500-FChoose it when the part is bent, formed or impact-loaded.

EN AC-51500-T5Choose it when strength drives the design, or when the part sees heat.
