Magnesium Alloy ZK60A-F vs ZK60A-T5

Magnesium Alloy · ZK60A temper comparison

ZK60A-F and ZK60A-T5 are two conditions of the same magnesium alloy grade, ZK60A: F (as fabricated) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. ZK60A-T5 is the stronger of the two: yield strength 305 MPa (44.2 ksi) against 260 MPa (37.7 ksi) for ZK60A-F, about 17% more; tensile strength follows at 365 MPa (52.9 ksi) vs 340 MPa (49.3 ksi). In exchange, ZK60A-F is the more ductile: elongation 14% versus 11% for ZK60A-T5, and ZK60A-T5 is harder (84 HB vs 75 HB).

ZK60A-FChoose it when the part is bent, formed or impact-loaded.

ZK60A-T5Choose it when strength drives the design.

ZK60A-F vs ZK60A-T5 — frequently asked

Is ZK60A-T5 stronger than ZK60A-F?

Yes. ZK60A-T5 has a typical yield strength of 305 MPa (44.2 ksi) against 260 MPa (37.7 ksi) for ZK60A-F — about 17% more. Tensile strength is 365 MPa (52.9 ksi) vs 340 MPa (49.3 ksi).

Which condition does FabDigit quote by default, F or T5?

F is the default ZK60A 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 ZK60A-F over ZK60A-T5?

Pick ZK60A-F when the part is bent, formed or impact-loaded. Pick ZK60A-T5 when strength drives the design.
