Aluminum 5070-H112 vs 5070-H32
Aluminum · 5070 temper comparison
5070-H112 and 5070-H32 are two conditions of the same aluminum grade, 5070: H112 (strain hardened from hot working only) versus H32 (strain hardened and stabilized, quarter hard). The chemistry is identical, so every difference below comes from the condition. 5070-H32 is the stronger of the two: yield strength 215 MPa (31.2 ksi) against 140 MPa (20.3 ksi) for 5070-H112, about 54% more; tensile strength follows at 305 MPa (44.2 ksi) vs 280 MPa (40.6 ksi). In exchange, 5070-H112 is the more ductile: elongation 16% versus 12% for 5070-H32, and 5070-H32 is harder (85 HB vs 73 HB).
5070-H112Choose it when the part is bent, formed or impact-loaded.
5070-H32Choose it when strength drives the design.
5070-H112 vs 5070-H32: 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.

5070-H112 vs 5070-H32 — frequently asked
Is 5070-H32 stronger than 5070-H112?
Yes. 5070-H32 has a typical yield strength of 215 MPa (31.2 ksi) against 140 MPa (20.3 ksi) for 5070-H112 — about 54% more. Tensile strength is 305 MPa (44.2 ksi) vs 280 MPa (40.6 ksi).
Which condition does FabDigit quote by default, H112 or H32?
H111 is the default 5070 condition in the FabDigit quote flow (neither H112 nor H32). 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, 5070-H112 or 5070-H32?
5070-H32, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 5070-H112.
