Aluminum ZL114A-T62 vs ZL114A-T7
Aluminum · ZL114A temper comparison
ZL114A-T62 and ZL114A-T7 are two conditions of the same aluminum grade, ZL114A: T62 (T6, heat treated by the user) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. ZL114A-T62 is the stronger of the two: yield strength 310 MPa (45 ksi) against 250 MPa (36.3 ksi) for ZL114A-T7, about 24% more; tensile strength follows at 380 MPa (55.1 ksi) vs 295 MPa (42.8 ksi). In exchange, ZL114A-T7 is the more ductile: elongation 6% versus 3% for ZL114A-T62, and ZL114A-T62 is harder (110 HB vs 85 HB). ZL114A-T7 runs hotter in service (200°C vs 150°C continuous).
ZL114A-T62Choose it when strength drives the design.
ZL114A-T7Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
ZL114A-T62 vs ZL114A-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.

ZL114A-T62 vs ZL114A-T7 — frequently asked
Is ZL114A-T62 stronger than ZL114A-T7?
Yes. ZL114A-T62 has a typical yield strength of 310 MPa (45 ksi) against 250 MPa (36.3 ksi) for ZL114A-T7 — about 24% more. Tensile strength is 380 MPa (55.1 ksi) vs 295 MPa (42.8 ksi).
Which condition does FabDigit quote by default, T62 or T7?
T6 is the default ZL114A condition in the FabDigit quote flow (neither T62 nor T7). 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, ZL114A-T62 or ZL114A-T7?
ZL114A-T62. Its machinability rates good (58/100) against fair (52/100) for ZL114A-T7; for welding the order is ZL114A-T7 first (very good, 75/100) then ZL114A-T62 (very good, 70/100).
