Aluminum 5182-H111 vs 5182-H18
Aluminum · 5182 temper comparison
5182-H111 and 5182-H18 are two conditions of the same aluminum grade, 5182: H111 (slightly strain hardened) versus H18 (strain hardened, full hard). The chemistry is identical, so every difference below comes from the condition. 5182-H18 is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 150 MPa (21.8 ksi) for 5182-H111, about 157% more; tensile strength follows at 410 MPa (59.5 ksi) vs 290 MPa (42.1 ksi). In exchange, 5182-H111 is the more ductile: elongation 19% versus 4% for 5182-H18, and 5182-H18 is harder (105 HB vs 75 HB).
5182-H111Choose it when the part is bent, formed or impact-loaded.
5182-H18Choose it when strength drives the design.
5182-H111 vs 5182-H18: 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.

5182-H111 vs 5182-H18 — frequently asked
Is 5182-H18 stronger than 5182-H111?
Yes. 5182-H18 has a typical yield strength of 385 MPa (55.8 ksi) against 150 MPa (21.8 ksi) for 5182-H111 — about 157% more. Tensile strength is 410 MPa (59.5 ksi) vs 290 MPa (42.1 ksi).
Which condition does FabDigit quote by default, H111 or H18?
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, 5182-H111 or 5182-H18?
5182-H18, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for 5182-H111; for welding the order is 5182-H111 first (excellent, 85/100) then 5182-H18 (very good, 78/100).
