Aluminum 8011A-H12 vs 8011A-H19
Aluminum · 8011A temper comparison
8011A-H12 and 8011A-H19 are two conditions of the same aluminum grade, 8011A: H12 (strain hardened, quarter hard) versus H19 (strain hardened, extra hard). The chemistry is identical, so every difference below comes from the condition. 8011A-H19 is the stronger of the two: yield strength 175 MPa (25.4 ksi) against 90 MPa (13.1 ksi) for 8011A-H12, about 94% more; tensile strength follows at 195 MPa (28.3 ksi) vs 120 MPa (17.4 ksi). In exchange, 8011A-H12 is the more ductile: elongation 10% versus 2% for 8011A-H19, and 8011A-H19 is harder (54 HB vs 34 HB). 8011A-H12 runs hotter in service (120°C vs 105°C continuous). On the shop floor, 8011A-H19 machines more easily (46 vs 35 out of 100).
8011A-H12Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
8011A-H19Choose it when strength drives the design, or when the part is machined in volume.
8011A-H12 vs 8011A-H19: 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.

8011A-H12 vs 8011A-H19 — frequently asked
Is 8011A-H19 stronger than 8011A-H12?
Yes. 8011A-H19 has a typical yield strength of 175 MPa (25.4 ksi) against 90 MPa (13.1 ksi) for 8011A-H12 — about 94% more. Tensile strength is 195 MPa (28.3 ksi) vs 120 MPa (17.4 ksi).
Which condition does FabDigit quote by default, H12 or H19?
H18 is the default 8011A condition in the FabDigit quote flow (neither H12 nor H19). 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, 8011A-H12 or 8011A-H19?
8011A-H19, by a small margin. Both rate fair for machinability — 46/100 against 35/100 for 8011A-H12; for welding the order is 8011A-H12 first (very good, 82/100) then 8011A-H19 (very good, 75/100).
