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.
