Aluminum EN AC-43200-T6 vs EN AC-43200-T64

Aluminum · EN AC-43200 temper comparison

EN AC-43200-T6 and EN AC-43200-T64 are two conditions of the same aluminum grade, EN AC-43200: T6 (solution heat treated and artificially aged) versus T64 (solution heat treated and under-aged). The chemistry is identical, so every difference below comes from the condition. EN AC-43200-T6 is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 150 MPa (21.8 ksi) for EN AC-43200-T64, about 47% more; tensile strength follows at 260 MPa (37.7 ksi) vs 210 MPa (30.5 ksi). In exchange, EN AC-43200-T64 is the more ductile: elongation 3% versus 1.5% for EN AC-43200-T6, and EN AC-43200-T6 is harder (90 HB vs 75 HB). EN AC-43200-T6 conducts heat better (150 W/m·K vs 130 W/m·K). On the shop floor, EN AC-43200-T6 welds better (good vs fair).

EN AC-43200-T6Choose it when strength drives the design, or when it will be welded.

EN AC-43200-T64Choose it when the part is bent, formed or impact-loaded.
