Aluminum 2014-H111 vs 2014-T351
Aluminum · 2014 temper comparison
2014-H111 and 2014-T351 are two conditions of the same aluminum grade, 2014: H111 (slightly strain hardened) versus T351 (T3, stress relieved by stretching). The chemistry is identical, so every difference below comes from the condition. 2014-T351 is the stronger of the two: yield strength 295 MPa (42.8 ksi) against 105 MPa (15.2 ksi) for 2014-H111, about 181% more; tensile strength follows at 440 MPa (63.8 ksi) vs 190 MPa (27.6 ksi). 2014-T351 is harder — 105 HB against 47 HB for 2014-H111 — which matters for wear surfaces and threads. 2014-H111 runs hotter in service (150°C vs 120°C continuous) and 2014-H111 conducts heat better (190 W/m·K vs 134 W/m·K). On the shop floor, 2014-T351 machines more easily (very good vs fair) and 2014-H111 forms better (very good vs fair).
2014-H111Choose it when the part sees heat.
2014-T351Choose it when strength drives the design, or when surface hardness matters.
2014-H111 vs 2014-T351: 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.

2014-H111 vs 2014-T351 — frequently asked
Is 2014-T351 stronger than 2014-H111?
Yes. 2014-T351 has a typical yield strength of 295 MPa (42.8 ksi) against 105 MPa (15.2 ksi) for 2014-H111 — about 181% more. Tensile strength is 440 MPa (63.8 ksi) vs 190 MPa (27.6 ksi).
Which condition does FabDigit quote by default, H111 or T351?
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, 2014-H111 or 2014-T351?
2014-T351. Its machinability rates very good (75/100) against fair (45/100) for 2014-H111; for welding the order is 2014-H111 first (poor, 25/100) then 2014-T351 (poor, 20/100).
