Aluminum 5010-H12 vs 5010-O
Aluminum · 5010 temper comparison
5010-H12 and 5010-O are two conditions of the same aluminum grade, 5010: H12 (strain hardened, quarter hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 5010-H12 is the stronger of the two: yield strength 95 MPa (13.8 ksi) against 40 MPa (5.8 ksi) for 5010-O, about 138% more; tensile strength follows at 115 MPa (16.7 ksi) vs 100 MPa (14.5 ksi). In exchange, 5010-O is the more ductile: elongation 27% versus 9% for 5010-H12, and 5010-H12 is harder (33 HB vs 26 HB). 5010-O runs hotter in service (200°C vs 120°C continuous).
5010-H12Choose it when strength drives the design.
5010-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5010-H12 vs 5010-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.

5010-H12 vs 5010-O — frequently asked
Is 5010-H12 stronger than 5010-O?
Yes. 5010-H12 has a typical yield strength of 95 MPa (13.8 ksi) against 40 MPa (5.8 ksi) for 5010-O — about 138% more. Tensile strength is 115 MPa (16.7 ksi) vs 100 MPa (14.5 ksi).
Which condition does FabDigit quote by default, H12 or O?
H14 is the default 5010 condition in the FabDigit quote flow (neither H12 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, 5010-H12 or 5010-O?
5010-H12, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for 5010-O.
