Magnesium Alloy ZE63A-F vs ZE63A-T6
Magnesium Alloy · ZE63A temper comparison
ZE63A-F and ZE63A-T6 are two conditions of the same magnesium alloy grade, ZE63A: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. ZE63A-T6 is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 145 MPa (21 ksi) for ZE63A-F, about 31% more; tensile strength follows at 300 MPa (43.5 ksi) vs 200 MPa (29 ksi). ZE63A-T6 is the more ductile: elongation 10% versus 3% for ZE63A-F, and ZE63A-T6 is harder (65 HB vs 55 HB).
ZE63A-T6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
ZE63A-F vs ZE63A-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.

ZE63A-F vs ZE63A-T6 — frequently asked
Is ZE63A-T6 stronger than ZE63A-F?
Yes. ZE63A-T6 has a typical yield strength of 190 MPa (27.6 ksi) against 145 MPa (21 ksi) for ZE63A-F — about 31% more. Tensile strength is 300 MPa (43.5 ksi) vs 200 MPa (29 ksi).
Which condition does FabDigit quote by default, F or T6?
T6 is the default ZE63A 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, ZE63A-F or ZE63A-T6?
ZE63A-F. Its weldability rates very good (75/100) against very good (70/100) for ZE63A-T6.
