Aluminum ER5254-AW vs ER5254-H14
Aluminum · ER5254 temper comparison
ER5254-AW and ER5254-H14 are two conditions of the same aluminum grade, ER5254: AW (as-welded deposit) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. ER5254-H14 is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 120 MPa (17.4 ksi) for ER5254-AW, about 92% more; tensile strength follows at 290 MPa (42.1 ksi) vs 250 MPa (36.3 ksi). In exchange, ER5254-AW is the more ductile: elongation 20% versus 8% for ER5254-H14, and ER5254-H14 is harder (73 HB vs 58 HB).
ER5254-AWChoose it when the part is bent, formed or impact-loaded.
ER5254-H14Choose it when strength drives the design.
ER5254-AW vs ER5254-H14: 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.
