Aluminum 392.0-F vs 392.0-T7
Aluminum · 392.0 temper comparison
392.0-F and 392.0-T7 are two conditions of the same aluminum grade, 392.0: F (as fabricated) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. Both yield at about 255 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus solution heat treated and overaged (stabilized)). 392.0-T7 runs hotter in service (250°C vs 200°C continuous).

392.0-F vs 392.0-T7: 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.

392.0-F vs 392.0-T7 — frequently asked
What is the difference between 392.0-F and 392.0-T7?
392.0-F and 392.0-T7 are two conditions of the same aluminum grade, 392.0: F (as fabricated) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. Both yield at about 255 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus solution heat treated and overaged (stabilized)).
Which condition does FabDigit quote by default, F or T7?
F is the default 392.0 condition in the FabDigit quote flow. 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.
When should I choose 392.0-F over 392.0-T7?
Pick 392.0-T7 when the part sees heat.
