Aluminum 5554-H112 vs 5554-H32
Aluminum · 5554 temper comparison
5554-H112 and 5554-H32 are two conditions of the same aluminum grade, 5554: 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. 5554-H32 is the stronger of the two: yield strength 200 MPa (29 ksi) against 130 MPa (18.9 ksi) for 5554-H112, about 54% more; tensile strength follows at 270 MPa (39.2 ksi) vs 250 MPa (36.3 ksi). 5554-H32 is harder — 73 HB against 65 HB for 5554-H112 — which matters for wear surfaces and threads. On the shop floor, 5554-H112 forms better (80 vs 70 out of 100).
5554-H32Choose it when strength drives the design, or when surface hardness matters.
5554-H112 vs 5554-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.

5554-H112 vs 5554-H32 — frequently asked
Is 5554-H32 stronger than 5554-H112?
Yes. 5554-H32 has a typical yield strength of 200 MPa (29 ksi) against 130 MPa (18.9 ksi) for 5554-H112 — about 54% more. Tensile strength is 270 MPa (39.2 ksi) vs 250 MPa (36.3 ksi).
Which condition does FabDigit quote by default, H112 or H32?
AS-WELDED is the default 5554 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, 5554-H112 or 5554-H32?
5554-H32, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 5554-H112.
