Aluminum 5059-H112 vs 5059-H116
Aluminum · 5059 temper comparison
5059-H112 and 5059-H116 are two conditions of the same aluminum grade, 5059: H112 (strain hardened from hot working only) versus H116 (strain hardened, corrosion-resistant marine temper). The chemistry is identical, so every difference below comes from the condition. 5059-H116 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 185 MPa (26.8 ksi) for 5059-H112, about 62% more; tensile strength follows at 400 MPa (58 ksi) vs 355 MPa (51.5 ksi). In exchange, 5059-H112 is the more ductile: elongation 20% versus 13% for 5059-H116, and 5059-H116 is harder (100 HB vs 95 HB).
5059-H112Choose it when the part is bent, formed or impact-loaded.
5059-H116Choose it when strength drives the design.
5059-H112 vs 5059-H116: 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-H112 vs 5059-H116 — frequently asked
Is 5059-H116 stronger than 5059-H112?
Yes. 5059-H116 has a typical yield strength of 300 MPa (43.5 ksi) against 185 MPa (26.8 ksi) for 5059-H112 — about 62% more. Tensile strength is 400 MPa (58 ksi) vs 355 MPa (51.5 ksi).
Which condition does FabDigit quote by default, H112 or H116?
H111 is the default 5059 condition in the FabDigit quote flow (neither H112 nor H116). 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-H112 or 5059-H116?
5059-H112, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 5059-H116.
