Aluminum 5042-H19 vs 5042-H28
Aluminum · 5042 temper comparison
5042-H19 and 5042-H28 are two conditions of the same aluminum grade, 5042: H19 (strain hardened, extra hard) versus H28 (strain hardened and partially annealed, full hard). The chemistry is identical, so every difference below comes from the condition. 5042-H19 is the stronger of the two: yield strength 331 MPa (48 ksi) against 305 MPa (44.2 ksi) for 5042-H28, about 9% more; tensile strength follows at 359 MPa (52.1 ksi) vs 340 MPa (49.3 ksi). In exchange, 5042-H28 is the more ductile: elongation 6% versus 4% for 5042-H19, and 5042-H19 is harder (100 HB vs 94 HB). 5042-H28 runs hotter in service (80°C vs 65°C continuous).
5042-H19Choose it when strength drives the design.
5042-H28Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5042-H19 vs 5042-H28: 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.

5042-H19 vs 5042-H28 — frequently asked
Is 5042-H19 stronger than 5042-H28?
Yes. 5042-H19 has a typical yield strength of 331 MPa (48 ksi) against 305 MPa (44.2 ksi) for 5042-H28 — about 9% more. Tensile strength is 359 MPa (52.1 ksi) vs 340 MPa (49.3 ksi).
Which condition does FabDigit quote by default, H19 or H28?
H19 is the default 5042 condition in the FabDigit quote flow. 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 5042-H19 over 5042-H28?
Pick 5042-H19 when strength drives the design. Pick 5042-H28 when the part is bent, formed or impact-loaded, or when the part sees heat.
