Aluminum ADC6-F vs ADC6-O
Aluminum · ADC6 temper comparison
ADC6-F and ADC6-O are two conditions of the same aluminum grade, ADC6: F (as fabricated) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. ADC6-F is the stronger of the two: yield strength 145 MPa (21 ksi) against 120 MPa (17.4 ksi) for ADC6-O, about 21% more; tensile strength follows at 265 MPa (38.4 ksi) vs 235 MPa (34.1 ksi). In exchange, ADC6-O is the more ductile: elongation 11% versus 8% for ADC6-F, and ADC6-F is harder (65 HB vs 58 HB).
ADC6-FChoose it when strength drives the design.
ADC6-OChoose it when the part is bent, formed or impact-loaded.
ADC6-F vs ADC6-O: 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.

ADC6-F vs ADC6-O — frequently asked
Is ADC6-F stronger than ADC6-O?
Yes. ADC6-F has a typical yield strength of 145 MPa (21 ksi) against 120 MPa (17.4 ksi) for ADC6-O — about 21% more. Tensile strength is 265 MPa (38.4 ksi) vs 235 MPa (34.1 ksi).
Which condition does FabDigit quote by default, F or O?
F is the default ADC6 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 ADC6-F over ADC6-O?
Pick ADC6-F when strength drives the design. Pick ADC6-O when the part is bent, formed or impact-loaded.
