Aluminum ADC6 HVDC-F vs ADC6-O
Aluminum · ADC6 temper comparison
ADC6 HVDC-F and ADC6-O are two conditions of the same aluminum grade, ADC6: HVDC-F (vacuum-assisted high-pressure die cast, as-cast) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. ADC6 HVDC-F is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 120 MPa (17.4 ksi) for ADC6-O, about 25% more; tensile strength follows at 280 MPa (40.6 ksi) vs 235 MPa (34.1 ksi). ADC6 HVDC-F is the more ductile: elongation 13% versus 11% for ADC6-O, and ADC6 HVDC-F is harder (66 HB vs 58 HB). On the shop floor, ADC6 HVDC-F welds better (good vs fair).
ADC6 HVDC-FChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
ADC6 HVDC-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 HVDC-F vs ADC6-O — frequently asked
Is ADC6 HVDC-F stronger than ADC6-O?
Yes. ADC6 HVDC-F has a typical yield strength of 150 MPa (21.8 ksi) against 120 MPa (17.4 ksi) for ADC6-O — about 25% more. Tensile strength is 280 MPa (40.6 ksi) vs 235 MPa (34.1 ksi).
Which condition does FabDigit quote by default, HVDC-F or O?
F is the default ADC6 condition in the FabDigit quote flow (neither HVDC-F nor O). 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, ADC6 HVDC-F or ADC6-O?
ADC6 HVDC-F, by a small margin. Both rate good for machinability — 67/100 against 62/100 for ADC6-O; for welding the order is ADC6 HVDC-F first (good, 60/100) then ADC6-O (fair, 48/100).
