Aluminum 5456-H112 vs 5456-H32
Aluminum · 5456 temper comparison
5456-H112 and 5456-H32 are two conditions of the same aluminum grade, 5456: 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. 5456-H32 is the stronger of the two: yield strength 255 MPa (37 ksi) against 165 MPa (23.9 ksi) for 5456-H112, about 55% more; tensile strength follows at 352 MPa (51.1 ksi) vs 310 MPa (45 ksi). In exchange, 5456-H112 is the more ductile: elongation 18% versus 16% for 5456-H32, and 5456-H32 is harder (90 HB vs 73 HB).

5456-H32Choose it when strength drives the design.
5456-H112 vs 5456-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.

5456-H112 vs 5456-H32 — frequently asked
Is 5456-H32 stronger than 5456-H112?
Yes. 5456-H32 has a typical yield strength of 255 MPa (37 ksi) against 165 MPa (23.9 ksi) for 5456-H112 — about 55% more. Tensile strength is 352 MPa (51.1 ksi) vs 310 MPa (45 ksi).
Which condition does FabDigit quote by default, H112 or H32?
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, 5456-H112 or 5456-H32?
5456-H32, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 5456-H112; for welding the order is 5456-H112 first (excellent, 90/100) then 5456-H32 (excellent, 85/100).
