Aluminum 1060-H111 vs 1060-O
Aluminum · 1060 temper comparison
1060-H111 and 1060-O are two conditions of the same aluminum grade, 1060: H111 (slightly strain hardened) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 1060-H111 is the stronger of the two: yield strength 32 MPa (4.64 ksi) against 28 MPa (4.06 ksi) for 1060-O, about 14% more. In exchange, 1060-O is the more ductile: elongation 43% versus 32% for 1060-H111, and 1060-H111 is harder (20 HB vs 19 HB). 1060-O runs hotter in service (200°C vs 180°C continuous).
1060-H111Choose it when strength drives the design.
1060-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1060-H111 vs 1060-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.

1060-H111 vs 1060-O — frequently asked
Is 1060-H111 stronger than 1060-O?
Yes. 1060-H111 has a typical yield strength of 32 MPa (4.64 ksi) against 28 MPa (4.06 ksi) for 1060-O — about 14% more. Tensile strength is 72 MPa (10.4 ksi) vs 70 MPa (10.2 ksi).
Which condition does FabDigit quote by default, H111 or O?
Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.
Which is easier to machine, 1060-H111 or 1060-O?
1060-H111, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for 1060-O.
