Aluminum 5110A-H19 vs 5110A-O
Aluminum · 5110A temper comparison
5110A-H19 and 5110A-O are two conditions of the same aluminum grade, 5110A: H19 (strain hardened, extra hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 5110A-H19 is the stronger of the two: yield strength 175 MPa (25.4 ksi) against 40 MPa (5.8 ksi) for 5110A-O, about 4.4 times as much; tensile strength follows at 190 MPa (27.6 ksi) vs 105 MPa (15.2 ksi). In exchange, 5110A-O is the more ductile: elongation 24% versus 2% for 5110A-H19, and 5110A-H19 is harder (54 HB vs 28 HB). 5110A-O runs hotter in service (200°C vs 120°C continuous). On the shop floor, 5110A-H19 machines more easily (fair vs poor) and 5110A-O welds better (excellent vs very good).
5110A-H19Choose it when strength drives the design, or when the part is machined in volume.
5110A-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5110A-H19 vs 5110A-O: 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.

5110A-H19 vs 5110A-O — frequently asked
Is 5110A-H19 stronger than 5110A-O?
Yes. 5110A-H19 has a typical yield strength of 175 MPa (25.4 ksi) against 40 MPa (5.8 ksi) for 5110A-O — about 4.4 times as much. Tensile strength is 190 MPa (27.6 ksi) vs 105 MPa (15.2 ksi).
Which condition does FabDigit quote by default, H19 or O?
H14 is the default 5110A condition in the FabDigit quote flow (neither H19 nor O). 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, 5110A-H19 or 5110A-O?
5110A-H19. Its machinability rates fair (50/100) against poor (28/100) for 5110A-O; for welding the order is 5110A-O first (excellent, 90/100) then 5110A-H19 (very good, 78/100).
