Magnesium Alloy ZM10-F vs ZM10-T4
Magnesium Alloy · ZM10 temper comparison
ZM10-F and ZM10-T4 are two conditions of the same magnesium alloy grade, ZM10: F (as fabricated) versus T4 (solution heat treated and naturally aged). The chemistry is identical, so every difference below comes from the condition. ZM10-T4 is the stronger of the two: tensile strength 255 MPa (37 ksi) against 165 MPa (23.9 ksi) for ZM10-F, about 55% more. ZM10-T4 is the more ductile: elongation 7% versus 2% for ZM10-F. ZM10-F conducts electricity better (12.5 % IACS vs 10.5 % IACS).
ZM10-T4Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
ZM10-F vs ZM10-T4: 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.

ZM10-F vs ZM10-T4 — frequently asked
Is ZM10-T4 stronger than ZM10-F?
Yes. ZM10-T4 has a typical tensile strength of 255 MPa (37 ksi) against 165 MPa (23.9 ksi) for ZM10-F — about 55% more.
Which condition does FabDigit quote by default, F or T4?
T6 is the default ZM10 condition in the FabDigit quote flow (neither F nor T4). 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 ZM10-F over ZM10-T4?
Pick ZM10-T4 when strength drives the design, or when the part is bent, formed or impact-loaded.
