Aluminum 1199-H14 vs 1199-H19
Aluminum · 1199 temper comparison
1199-H14 and 1199-H19 are two conditions of the same aluminum grade, 1199: H14 (strain hardened, half hard) versus H19 (strain hardened, extra hard). The chemistry is identical, so every difference below comes from the condition. 1199-H19 is the stronger of the two: yield strength 120 MPa (17.4 ksi) against 70 MPa (10.2 ksi) for 1199-H14, about 71% more; tensile strength follows at 130 MPa (18.9 ksi) vs 80 MPa (11.6 ksi). In exchange, 1199-H14 is the more ductile: elongation 10% versus 2% for 1199-H19, and 1199-H19 is harder (33 HB vs 23 HB). 1199-H14 runs hotter in service (100°C vs 70°C continuous).
1199-H14Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1199-H19Choose it when strength drives the design.
1199-H14 vs 1199-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.
