Aluminum 5457-H26 vs 5457-H32
Aluminum · 5457 temper comparison
5457-H26 and 5457-H32 are two conditions of the same aluminum grade, 5457: H26 (strain hardened and partially annealed, three-quarter hard) versus H32 (strain hardened and stabilized, quarter hard). The chemistry is identical, so every difference below comes from the condition. 5457-H26 is the stronger of the two: yield strength 175 MPa (25.4 ksi) against 130 MPa (18.9 ksi) for 5457-H32, about 35% more; tensile strength follows at 195 MPa (28.3 ksi) vs 160 MPa (23.2 ksi). In exchange, 5457-H32 is the more ductile: elongation 16% versus 9% for 5457-H26, and 5457-H26 is harder (52 HB vs 42 HB).
5457-H26Choose it when strength drives the design.
5457-H32Choose it when the part is bent, formed or impact-loaded.
5457-H26 vs 5457-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.

5457-H26 vs 5457-H32 — frequently asked
Is 5457-H26 stronger than 5457-H32?
Yes. 5457-H26 has a typical yield strength of 175 MPa (25.4 ksi) against 130 MPa (18.9 ksi) for 5457-H32 — about 35% more. Tensile strength is 195 MPa (28.3 ksi) vs 160 MPa (23.2 ksi).
Which condition does FabDigit quote by default, H26 or H32?
H25 is the default 5457 condition in the FabDigit quote flow (neither H26 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, 5457-H26 or 5457-H32?
5457-H26, by a small margin. Both rate fair for machinability — 45/100 against 36/100 for 5457-H32.
