Aluminum 1100-H112 vs 1100-O
Aluminum · 1100 temper comparison
1100-H112 and 1100-O are two conditions of the same aluminum grade, 1100: H112 (strain hardened from hot working only) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 1100-H112 is the stronger of the two: yield strength 45 MPa (6.53 ksi) against 34 MPa (4.93 ksi) for 1100-O, about 32% more; tensile strength follows at 95 MPa (13.8 ksi) vs 90 MPa (13.1 ksi). In exchange, 1100-O is the more ductile: elongation 40% versus 25% for 1100-H112, and 1100-H112 is harder (25 HB vs 23 HB).
1100-H112Choose it when strength drives the design.
1100-OChoose it when the part is bent, formed or impact-loaded.
1100-H112 vs 1100-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.

1100-H112 vs 1100-O — frequently asked
Is 1100-H112 stronger than 1100-O?
Yes. 1100-H112 has a typical yield strength of 45 MPa (6.53 ksi) against 34 MPa (4.93 ksi) for 1100-O — about 32% more. Tensile strength is 95 MPa (13.8 ksi) vs 90 MPa (13.1 ksi).
Which condition does FabDigit quote by default, H112 or O?
Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.
When should I choose 1100-H112 over 1100-O?
Pick 1100-H112 when strength drives the design. Pick 1100-O when the part is bent, formed or impact-loaded.
