Aluminum 324.0-T5 vs 324.0-T62
Aluminum · 324.0 temper comparison
324.0-T5 and 324.0-T62 are two conditions of the same aluminum grade, 324.0: T5 (cooled from hot working and artificially aged) versus T62 (T6, heat treated by the user). The chemistry is identical, so every difference below comes from the condition. 324.0-T62 is the stronger of the two: yield strength 248 MPa (36 ksi) against 193 MPa (28 ksi) for 324.0-T5, about 28% more; tensile strength follows at 296 MPa (42.9 ksi) vs 248 MPa (36 ksi). 324.0-T62 is harder — 105 HB against 90 HB for 324.0-T5 — which matters for wear surfaces and threads.
324.0-T62Choose it when strength drives the design, or when surface hardness matters.
324.0-T5 vs 324.0-T62: 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.

324.0-T5 vs 324.0-T62 — frequently asked
Is 324.0-T62 stronger than 324.0-T5?
Yes. 324.0-T62 has a typical yield strength of 248 MPa (36 ksi) against 193 MPa (28 ksi) for 324.0-T5 — about 28% more. Tensile strength is 296 MPa (42.9 ksi) vs 248 MPa (36 ksi).
Which condition does FabDigit quote by default, T5 or T62?
T5 is the default 324.0 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, 324.0-T5 or 324.0-T62?
324.0-T62, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 324.0-T5.
