Aluminum 5019-H111 vs 5019-H34
Aluminum · 5019 temper comparison
5019-H111 and 5019-H34 are two conditions of the same aluminum grade, 5019: H111 (slightly strain hardened) versus H34 (strain hardened and stabilized, half hard). The chemistry is identical, so every difference below comes from the condition. 5019-H34 is the stronger of the two: yield strength 285 MPa (41.3 ksi) against 145 MPa (21 ksi) for 5019-H111, about 97% more; tensile strength follows at 370 MPa (53.7 ksi) vs 290 MPa (42.1 ksi). In exchange, 5019-H111 is the more ductile: elongation 21% versus 8% for 5019-H34, and 5019-H34 is harder (100 HB vs 72 HB). On the shop floor, 5019-H34 machines more easily (50 vs 40 out of 100).
5019-H111Choose it when the part is bent, formed or impact-loaded.
5019-H34Choose it when strength drives the design, or when the part is machined in volume.
5019-H111 vs 5019-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.

5019-H111 vs 5019-H34 — frequently asked
Is 5019-H34 stronger than 5019-H111?
Yes. 5019-H34 has a typical yield strength of 285 MPa (41.3 ksi) against 145 MPa (21 ksi) for 5019-H111 — about 97% more. Tensile strength is 370 MPa (53.7 ksi) vs 290 MPa (42.1 ksi).
Which condition does FabDigit quote by default, H111 or H34?
Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.
Which is easier to machine, 5019-H111 or 5019-H34?
5019-H34, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for 5019-H111; for welding the order is 5019-H111 first (excellent, 85/100) then 5019-H34 (very good, 80/100).
