Aluminum ZL102-F vs ZL102-T2

Aluminum · ZL102 temper comparison

ZL102-F and ZL102-T2 are two conditions of the same aluminum grade, ZL102: F (as fabricated) versus T2 (cooled from hot working, cold worked and naturally aged). The chemistry is identical, so every difference below comes from the condition. ZL102-F is the stronger of the two: yield strength 80 MPa (11.6 ksi) against 70 MPa (10.2 ksi) for ZL102-T2, about 14% more; tensile strength follows at 170 MPa (24.7 ksi) vs 155 MPa (22.5 ksi). In exchange, ZL102-T2 is the more ductile: elongation 6% versus 5% for ZL102-F, and ZL102-F is harder (55 HB vs 52 HB).

ZL102-FChoose it when strength drives the design.

ZL102-T2Choose it when the part is bent, formed or impact-loaded.

ZL102-F vs ZL102-T2 — frequently asked

Is ZL102-F stronger than ZL102-T2?

Yes. ZL102-F has a typical yield strength of 80 MPa (11.6 ksi) against 70 MPa (10.2 ksi) for ZL102-T2 — about 14% more. Tensile strength is 170 MPa (24.7 ksi) vs 155 MPa (22.5 ksi).

Which condition does FabDigit quote by default, F or T2?

F is the default ZL102 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 ZL102-F over ZL102-T2?

Pick ZL102-F when strength drives the design. Pick ZL102-T2 when the part is bent, formed or impact-loaded.
