Aluminum 5654-AW vs 5654-H32
Aluminum · 5654 temper comparison
5654-AW and 5654-H32 are two conditions of the same aluminum grade, 5654: AW (as-welded deposit) versus H32 (strain hardened and stabilized, quarter hard). The chemistry is identical, so every difference below comes from the condition. 5654-H32 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 105 MPa (15.2 ksi) for 5654-AW, about 95% more; tensile strength follows at 270 MPa (39.2 ksi) vs 215 MPa (31.2 ksi). In exchange, 5654-AW is the more ductile: elongation 17% versus 15% for 5654-H32, and 5654-H32 is harder (67 HB vs 52 HB).

5654-AW vs 5654-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.

5654-AW vs 5654-H32 — frequently asked
Is 5654-H32 stronger than 5654-AW?
Yes. 5654-H32 has a typical yield strength of 205 MPa (29.7 ksi) against 105 MPa (15.2 ksi) for 5654-AW — about 95% more. Tensile strength is 270 MPa (39.2 ksi) vs 215 MPa (31.2 ksi).
Which condition does FabDigit quote by default, AW or H32?
O is the default 5654 condition in the FabDigit quote flow (neither AW 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, 5654-AW or 5654-H32?
5654-H32, by a small margin. Both rate fair for machinability — 42/100 against 35/100 for 5654-AW.
