Aluminum 6053-F vs 6053-T62
Aluminum · 6053 temper comparison
6053-F and 6053-T62 are two conditions of the same aluminum grade, 6053: F (as fabricated) versus T62 (T6, heat treated by the user). The chemistry is identical, so every difference below comes from the condition. 6053-T62 is the stronger of the two: yield strength 215 MPa (31.2 ksi) against 90 MPa (13.1 ksi) for 6053-F, about 139% more; tensile strength follows at 255 MPa (37 ksi) vs 150 MPa (21.8 ksi). In exchange, 6053-F is the more ductile: elongation 20% versus 13% for 6053-T62, and 6053-T62 is harder (80 HB vs 42 HB). On the shop floor, 6053-T62 machines more easily (good vs fair).
6053-FChoose it when the part is bent, formed or impact-loaded.
6053-T62Choose it when strength drives the design, or when the part is machined in volume.
6053-F vs 6053-T62: 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.

6053-F vs 6053-T62 — frequently asked
Is 6053-T62 stronger than 6053-F?
Yes. 6053-T62 has a typical yield strength of 215 MPa (31.2 ksi) against 90 MPa (13.1 ksi) for 6053-F — about 139% more. Tensile strength is 255 MPa (37 ksi) vs 150 MPa (21.8 ksi).
Which condition does FabDigit quote by default, F or T62?
T6 is the default 6053 condition in the FabDigit quote flow (neither F nor T62). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 6053-F or 6053-T62?
6053-T62. Its machinability rates good (55/100) against fair (35/100) for 6053-F.
