Aluminum 332.0-T5 vs 332.0-T7
Aluminum · 332.0 temper comparison
332.0-T5 and 332.0-T7 are two conditions of the same aluminum grade, 332.0: T5 (cooled from hot working and artificially aged) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. 332.0-T5 is the stronger of the two: yield strength 193 MPa (28 ksi) against 170 MPa (24.7 ksi) for 332.0-T7, about 14% more; tensile strength follows at 248 MPa (36 ksi) vs 225 MPa (32.6 ksi). In exchange, 332.0-T7 is the more ductile: elongation 1.5% versus 1% for 332.0-T5, and 332.0-T5 is harder (105 HB vs 95 HB). 332.0-T7 conducts electricity better (29 % IACS vs 26 % IACS).
332.0-T5Choose it when strength drives the design.
332.0-T7Choose it when the part is bent, formed or impact-loaded.
332.0-T5 vs 332.0-T7: 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.

332.0-T5 vs 332.0-T7 — frequently asked
Is 332.0-T5 stronger than 332.0-T7?
Yes. 332.0-T5 has a typical yield strength of 193 MPa (28 ksi) against 170 MPa (24.7 ksi) for 332.0-T7 — about 14% more. Tensile strength is 248 MPa (36 ksi) vs 225 MPa (32.6 ksi).
Which condition does FabDigit quote by default, T5 or T7?
T5 is the default 332.0 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.
When should I choose 332.0-T5 over 332.0-T7?
Pick 332.0-T5 when strength drives the design. Pick 332.0-T7 when the part is bent, formed or impact-loaded.
