Aluminum 2014-H111 vs 2014-T4
Aluminum · 2014 temper comparison
2014-H111 and 2014-T4 are two conditions of the same aluminum grade, 2014: H111 (slightly strain hardened) versus T4 (solution heat treated and naturally aged). The chemistry is identical, so every difference below comes from the condition. 2014-T4 is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 105 MPa (15.2 ksi) for 2014-H111, about 176% more; tensile strength follows at 425 MPa (61.6 ksi) vs 190 MPa (27.6 ksi). 2014-T4 is the more ductile: elongation 20% versus 17% for 2014-H111, and 2014-T4 is harder (105 HB vs 47 HB). 2014-H111 runs hotter in service (150°C vs 100°C continuous) and 2014-H111 conducts heat better (190 W/m·K vs 134 W/m·K). On the shop floor, 2014-T4 machines more easily (very good vs fair).
2014-H111Choose it when the part sees heat.
2014-T4Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
2014-H111 vs 2014-T4: 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.
