Aluminum ADC10Z vs ADC10-O
Aluminum · ADC10 temper comparison
ADC10Z and ADC10-O are two conditions of the same aluminum grade, ADC10: ADC10Z (high-Zn tolerance variant) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. ADC10Z is the stronger of the two: yield strength 165 MPa (23.9 ksi) against 120 MPa (17.4 ksi) for ADC10-O, about 38% more; tensile strength follows at 320 MPa (46.4 ksi) vs 250 MPa (36.3 ksi). In exchange, ADC10-O is the more ductile: elongation 5% versus 2.5% for ADC10Z, and ADC10Z is harder (82 HB vs 65 HB). ADC10-O runs hotter in service (200°C vs 150°C continuous) and ADC10-O conducts heat better (110 W/m·K vs 92 W/m·K). On the shop floor, ADC10-O welds better (30 vs 20 out of 100).
ADC10ZChoose it when strength drives the design.
ADC10-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
ADC10Z vs ADC10-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.

ADC10Z vs ADC10-O — frequently asked
Is ADC10Z stronger than ADC10-O?
Yes. ADC10Z has a typical yield strength of 165 MPa (23.9 ksi) against 120 MPa (17.4 ksi) for ADC10-O — about 38% more. Tensile strength is 320 MPa (46.4 ksi) vs 250 MPa (36.3 ksi).
Which condition does FabDigit quote by default, ADC10Z or O?
F is the default ADC10 condition in the FabDigit quote flow (neither ADC10Z 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, ADC10Z or ADC10-O?
ADC10Z, by a small margin. Both rate very good for machinability — 76/100 against 70/100 for ADC10-O; for welding the order is ADC10-O first (poor, 30/100) then ADC10Z (poor, 20/100).
