Magnesium Alloy MgMn2-F vs MgMn2-H24
Magnesium Alloy · MgMn2 temper comparison
MgMn2-F and MgMn2-H24 are two conditions of the same magnesium alloy grade, MgMn2: F (as fabricated) versus H24 (strain hardened and partially annealed, half hard). The chemistry is identical, so every difference below comes from the condition. Both yield at about 180 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus strain hardened and partially annealed, half hard). MgMn2-F is the more ductile: elongation 12% versus 6% for MgMn2-H24, and MgMn2-H24 is harder (48 HB vs 44 HB). MgMn2-F runs hotter in service (150°C vs 120°C continuous).
MgMn2-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
MgMn2-F vs MgMn2-H24: 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.

MgMn2-F vs MgMn2-H24 — frequently asked
What is the difference between MgMn2-F and MgMn2-H24?
MgMn2-F and MgMn2-H24 are two conditions of the same magnesium alloy grade, MgMn2: F (as fabricated) versus H24 (strain hardened and partially annealed, half hard). The chemistry is identical, so every difference below comes from the condition. Both yield at about 180 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus strain hardened and partially annealed, half hard).
Which condition does FabDigit quote by default, F or H24?
F is the default MgMn2 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.
Which welds better, MgMn2-F or MgMn2-H24?
MgMn2-F. Its weldability rates excellent (88/100) against very good (82/100) for MgMn2-H24.
