Aluminum 535-F vs 535-T6
Aluminum · 535 temper comparison
535-F and 535-T6 are two conditions of the same aluminum grade, 535: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. 535-T6 is the stronger of the two: yield strength 170 MPa (24.7 ksi) against 140 MPa (20.3 ksi) for 535-F, about 21% more; tensile strength follows at 290 MPa (42.1 ksi) vs 275 MPa (39.9 ksi). In exchange, 535-F is the more ductile: elongation 13% versus 6% for 535-T6, and 535-T6 is harder (80 HB vs 70 HB). 535-F runs hotter in service (100°C vs 80°C continuous). On the shop floor, 535-F welds better (very good vs good).
535-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
535-T6Choose it when strength drives the design.
535-F vs 535-T6: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
