Aluminum ZL116-F vs ZL116-T5
Aluminum · ZL116 temper comparison
ZL116-F and ZL116-T5 are two conditions of the same aluminum grade, ZL116: F (as fabricated) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. ZL116-T5 is the stronger of the two: yield strength 255 MPa (37 ksi) against 110 MPa (16 ksi) for ZL116-F, about 132% more; tensile strength follows at 335 MPa (48.6 ksi) vs 195 MPa (28.3 ksi). ZL116-T5 is harder — 90 HB against 60 HB for ZL116-F — which matters for wear surfaces and threads.
ZL116-T5Choose it when strength drives the design, or when surface hardness matters.
ZL116-F vs ZL116-T5: 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.

ZL116-F vs ZL116-T5 — frequently asked
Is ZL116-T5 stronger than ZL116-F?
Yes. ZL116-T5 has a typical yield strength of 255 MPa (37 ksi) against 110 MPa (16 ksi) for ZL116-F — about 132% more. Tensile strength is 335 MPa (48.6 ksi) vs 195 MPa (28.3 ksi).
Which condition does FabDigit quote by default, F or T5?
T5 is the default ZL116 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, ZL116-F or ZL116-T5?
ZL116-T5. Its machinability rates good (55/100) against fair (50/100) for ZL116-F.
