Magnesium Alloy ZE41-F vs ZE41-T5

Magnesium Alloy · ZE41 temper comparison

ZE41-F and ZE41-T5 are two conditions of the same magnesium alloy grade, ZE41: F (as fabricated) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. ZE41-T5 is the stronger of the two: yield strength 140 MPa (20.3 ksi) against 115 MPa (16.7 ksi) for ZE41-F, about 22% more; tensile strength follows at 205 MPa (29.7 ksi) vs 170 MPa (24.7 ksi). ZE41-T5 is the more ductile: elongation 3.5% versus 3% for ZE41-F, and ZE41-T5 is harder (62 HB vs 55 HB). ZE41-T5 runs hotter in service (150°C vs 120°C continuous).

ZE41-T5Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

ZE41-F vs ZE41-T5 — frequently asked

Is ZE41-T5 stronger than ZE41-F?

Yes. ZE41-T5 has a typical yield strength of 140 MPa (20.3 ksi) against 115 MPa (16.7 ksi) for ZE41-F — about 22% more. Tensile strength is 205 MPa (29.7 ksi) vs 170 MPa (24.7 ksi).

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

T5 is the default ZE41 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 ZE41-F over ZE41-T5?

Pick ZE41-T5 when strength drives the design, or when the part is bent, formed or impact-loaded.
