Aluminum 5059-H111 vs 5059-H112
Aluminum · 5059 temper comparison
5059-H111 and 5059-H112 are two conditions of the same aluminum grade, 5059: H111 (slightly strain hardened) versus H112 (strain hardened from hot working only). The chemistry is identical, so every difference below comes from the condition. Both yield at about 190 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (slightly strain hardened versus strain hardened from hot working only). 5059-H112 is harder — 95 HB against 85 HB for 5059-H111 — which matters for wear surfaces and threads. On the shop floor, 5059-H111 forms better (very good vs good).

5059-H111 vs 5059-H112: 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.

5059-H111 vs 5059-H112 — frequently asked
What is the difference between 5059-H111 and 5059-H112?
5059-H111 and 5059-H112 are two conditions of the same aluminum grade, 5059: H111 (slightly strain hardened) versus H112 (strain hardened from hot working only). The chemistry is identical, so every difference below comes from the condition. Both yield at about 190 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (slightly strain hardened versus strain hardened from hot working only).
Which condition does FabDigit quote by default, H111 or H112?
H111 is the default 5059 condition in the FabDigit quote flow. 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, 5059-H111 or 5059-H112?
5059-H112, by a small margin. Both rate fair for machinability — 50/100 against 42/100 for 5059-H111.
