Aluminum ADC14-F vs ADC14-T7
Aluminum · ADC14 temper comparison
ADC14-F and ADC14-T7 are two conditions of the same aluminum grade, ADC14: F (as fabricated) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. ADC14-T7 is the stronger of the two: yield strength 255 MPa (37 ksi) against 240 MPa (34.8 ksi) for ADC14-F, about 6% more. ADC14-T7 runs hotter in service (230°C vs 200°C continuous).
ADC14-T7Choose it when strength drives the design, or when the part sees heat.
ADC14-F vs ADC14-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.

ADC14-F vs ADC14-T7 — frequently asked
Is ADC14-T7 stronger than ADC14-F?
Yes. ADC14-T7 has a typical yield strength of 255 MPa (37 ksi) against 240 MPa (34.8 ksi) for ADC14-F — about 6% more. Tensile strength is 265 MPa (38.4 ksi) vs 280 MPa (40.6 ksi).
Which condition does FabDigit quote by default, F or T7?
F is the default ADC14 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 ADC14-F over ADC14-T7?
Pick ADC14-T7 when strength drives the design, or when the part sees heat.
