Aluminum ER5554-H32 vs ER5554-H34
Aluminum · ER5554 temper comparison
ER5554-H32 and ER5554-H34 are two conditions of the same aluminum grade, ER5554: H32 (strain hardened and stabilized, quarter hard) versus H34 (strain hardened and stabilized, half hard). The chemistry is identical, so every difference below comes from the condition. ER5554-H34 is the stronger of the two: yield strength 214 MPa (31 ksi) against 193 MPa (28 ksi) for ER5554-H32, about 11% more; tensile strength follows at 290 MPa (42.1 ksi) vs 269 MPa (39 ksi). In exchange, ER5554-H32 is the more ductile: elongation 15% versus 12% for ER5554-H34, and ER5554-H34 is harder (81 HB vs 73 HB).
ER5554-H32Choose it when the part is bent, formed or impact-loaded.
ER5554-H34Choose it when strength drives the design.
ER5554-H32 vs ER5554-H34: 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.

ER5554-H32 vs ER5554-H34 — frequently asked
Is ER5554-H34 stronger than ER5554-H32?
Yes. ER5554-H34 has a typical yield strength of 214 MPa (31 ksi) against 193 MPa (28 ksi) for ER5554-H32 — about 11% more. Tensile strength is 290 MPa (42.1 ksi) vs 269 MPa (39 ksi).
Which condition does FabDigit quote by default, H32 or H34?
AW is the default ER5554 condition in the FabDigit quote flow (neither H32 nor H34). 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.
When should I choose ER5554-H32 over ER5554-H34?
Pick ER5554-H32 when the part is bent, formed or impact-loaded. Pick ER5554-H34 when strength drives the design.
