Aluminum ZL114A-T4 vs ZL114A-T62

Aluminum · ZL114A temper comparison

ZL114A-T4 and ZL114A-T62 are two conditions of the same aluminum grade, ZL114A: T4 (solution heat treated and naturally aged) versus T62 (T6, heat treated by the user). 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 130 MPa (18.9 ksi) for ZL114A-T4, about 138% more; tensile strength follows at 380 MPa (55.1 ksi) vs 250 MPa (36.3 ksi). In exchange, ZL114A-T4 is the more ductile: elongation 10% versus 3% for ZL114A-T62, and ZL114A-T62 is harder (110 HB vs 65 HB). ZL114A-T62 runs hotter in service (150°C vs 120°C continuous).

ZL114A-T4Choose it when the part is bent, formed or impact-loaded.

ZL114A-T62Choose it when strength drives the design, or when the part sees heat.

ZL114A-T4 vs ZL114A-T62 — frequently asked

Is ZL114A-T62 stronger than ZL114A-T4?

Yes. ZL114A-T62 has a typical yield strength of 310 MPa (45 ksi) against 130 MPa (18.9 ksi) for ZL114A-T4 — about 138% more. Tensile strength is 380 MPa (55.1 ksi) vs 250 MPa (36.3 ksi).

Which condition does FabDigit quote by default, T4 or T62?

T6 is the default ZL114A condition in the FabDigit quote flow (neither T4 nor T62). 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-T4 or ZL114A-T62?

ZL114A-T62. Its machinability rates good (58/100) against fair (50/100) for ZL114A-T4; for welding the order is ZL114A-T4 first (very good, 75/100) then ZL114A-T62 (very good, 70/100).
