Magnesium Alloy ZE41-F vs ZE41-T6
Magnesium Alloy · ZE41 temper comparison
ZE41-F and ZE41-T6 are two conditions of the same magnesium alloy grade, ZE41: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. ZE41-T6 is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 115 MPa (16.7 ksi) for ZE41-F, about 30% more; tensile strength follows at 215 MPa (31.2 ksi) vs 170 MPa (24.7 ksi). ZE41-T6 is harder — 66 HB against 55 HB for ZE41-F — which matters for wear surfaces and threads. ZE41-T6 runs hotter in service (150°C vs 120°C continuous). On the shop floor, ZE41-F welds better (very good vs good).
ZE41-FChoose it when it will be welded.
ZE41-T6Choose it when strength drives the design, or when surface hardness matters.
ZE41-F vs ZE41-T6: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all magnesium alloy 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.

ZE41-F vs ZE41-T6 — frequently asked
Is ZE41-T6 stronger than ZE41-F?
Yes. ZE41-T6 has a typical yield strength of 150 MPa (21.8 ksi) against 115 MPa (16.7 ksi) for ZE41-F — about 30% more. Tensile strength is 215 MPa (31.2 ksi) vs 170 MPa (24.7 ksi).
Which condition does FabDigit quote by default, F or T6?
T5 is the default ZE41 condition in the FabDigit quote flow (neither F nor T6). 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 welds better, ZE41-F or ZE41-T6?
ZE41-F. Its weldability rates very good (72/100) against good (62/100) for ZE41-T6.
