Aluminum 8177-F vs 8177-H14
Aluminum · 8177 temper comparison
8177-F and 8177-H14 are two conditions of the same aluminum grade, 8177: F (as fabricated) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. 8177-H14 is the stronger of the two: yield strength 105 MPa (15.2 ksi) against 55 MPa (7.98 ksi) for 8177-F, about 91% more; tensile strength follows at 128 MPa (18.6 ksi) vs 105 MPa (15.2 ksi). In exchange, 8177-F is the more ductile: elongation 22% versus 10% for 8177-H14, and 8177-H14 is harder (32 HB vs 25 HB).
8177-FChoose it when the part is bent, formed or impact-loaded.
8177-H14Choose it when strength drives the design.
8177-F vs 8177-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.

8177-F vs 8177-H14 — frequently asked
Is 8177-H14 stronger than 8177-F?
Yes. 8177-H14 has a typical yield strength of 105 MPa (15.2 ksi) against 55 MPa (7.98 ksi) for 8177-F — about 91% more. Tensile strength is 128 MPa (18.6 ksi) vs 105 MPa (15.2 ksi).
Which condition does FabDigit quote by default, F or H14?
O is the default 8177 condition in the FabDigit quote flow (neither F 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, 8177-F or 8177-H14?
8177-H14, by a small margin. Both rate poor for machinability — 33/100 against 28/100 for 8177-F.
