Aluminum 5088-H112 vs 5088-H14
Aluminum · 5088 temper comparison
5088-H112 and 5088-H14 are two conditions of the same aluminum grade, 5088: H112 (strain hardened from hot working only) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. 5088-H14 is the stronger of the two: yield strength 285 MPa (41.3 ksi) against 170 MPa (24.7 ksi) for 5088-H112, about 68% more; tensile strength follows at 365 MPa (52.9 ksi) vs 300 MPa (43.5 ksi). In exchange, 5088-H112 is the more ductile: elongation 14% versus 7% for 5088-H14, and 5088-H14 is harder (99 HB vs 76 HB). 5088-H112 runs hotter in service (65°C vs 50°C continuous).
5088-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5088-H14Choose it when strength drives the design.
5088-H112 vs 5088-H14: 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.

5088-H112 vs 5088-H14 — frequently asked
Is 5088-H14 stronger than 5088-H112?
Yes. 5088-H14 has a typical yield strength of 285 MPa (41.3 ksi) against 170 MPa (24.7 ksi) for 5088-H112 — about 68% more. Tensile strength is 365 MPa (52.9 ksi) vs 300 MPa (43.5 ksi).
Which condition does FabDigit quote by default, H112 or H14?
H116 is the default 5088 condition in the FabDigit quote flow (neither H112 nor H14). 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, 5088-H112 or 5088-H14?
5088-H14, by a small margin. Both rate fair for machinability — 49/100 against 40/100 for 5088-H112; for welding the order is 5088-H112 first (excellent, 90/100) then 5088-H14 (very good, 84/100).
