Aluminum 5040-H112 vs 5040-H22
Aluminum · 5040 temper comparison
5040-H112 and 5040-H22 are two conditions of the same aluminum grade, 5040: H112 (strain hardened from hot working only) versus H22 (strain hardened and partially annealed, quarter hard). The chemistry is identical, so every difference below comes from the condition. 5040-H22 is the stronger of the two: yield strength 125 MPa (18.1 ksi) against 70 MPa (10.2 ksi) for 5040-H112, about 79% more; tensile strength follows at 165 MPa (23.9 ksi) vs 150 MPa (21.8 ksi). In exchange, 5040-H112 is the more ductile: elongation 16% versus 12% for 5040-H22, and 5040-H22 is harder (44 HB vs 40 HB). 5040-H112 runs hotter in service (150°C vs 120°C continuous).
5040-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5040-H22Choose it when strength drives the design.
5040-H112 vs 5040-H22: 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.

5040-H112 vs 5040-H22 — frequently asked
Is 5040-H22 stronger than 5040-H112?
Yes. 5040-H22 has a typical yield strength of 125 MPa (18.1 ksi) against 70 MPa (10.2 ksi) for 5040-H112 — about 79% more. Tensile strength is 165 MPa (23.9 ksi) vs 150 MPa (21.8 ksi).
Which condition does FabDigit quote by default, H112 or H22?
H34 is the default 5040 condition in the FabDigit quote flow (neither H112 nor H22). 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.
When should I choose 5040-H112 over 5040-H22?
Pick 5040-H112 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick 5040-H22 when strength drives the design.
