Aluminum A360-F vs A360-T6

Aluminum · A360 temper comparison

A360-F and A360-T6 are two conditions of the same aluminum grade, A360: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. A360-T6 is the stronger of the two: yield strength 235 MPa (34.1 ksi) against 165 MPa (23.9 ksi) for A360-F, about 42% more; tensile strength follows at 335 MPa (48.6 ksi) vs 317 MPa (46 ksi). A360-T6 is the more ductile: elongation 8% versus 3.5% for A360-F, and A360-T6 is harder (100 HB vs 75 HB). A360-T6 conducts heat better (155 W/m·K vs 113 W/m·K).

A360-T6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
