Magnesium Alloy WE54A-F vs WE54A-T6
Magnesium Alloy · WE54A temper comparison
WE54A-F and WE54A-T6 are two conditions of the same magnesium alloy grade, WE54A: F (as fabricated) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. WE54A-T6 is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 105 MPa (15.2 ksi) for WE54A-F, about 81% more; tensile strength follows at 275 MPa (39.9 ksi) vs 190 MPa (27.6 ksi). In exchange, WE54A-F is the more ductile: elongation 5% versus 4% for WE54A-T6, and WE54A-T6 is harder (85 HB vs 60 HB). WE54A-T6 runs hotter in service (250°C vs 150°C continuous) and WE54A-T6 conducts electricity better (10 % IACS vs 9 % IACS).
WE54A-FChoose it when the part is bent, formed or impact-loaded.
WE54A-T6Choose it when strength drives the design, or when the part sees heat.
WE54A-F vs WE54A-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.

WE54A-F vs WE54A-T6 — frequently asked
Is WE54A-T6 stronger than WE54A-F?
Yes. WE54A-T6 has a typical yield strength of 190 MPa (27.6 ksi) against 105 MPa (15.2 ksi) for WE54A-F — about 81% more. Tensile strength is 275 MPa (39.9 ksi) vs 190 MPa (27.6 ksi).
Which condition does FabDigit quote by default, F or T6?
T6 is the default WE54A 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, WE54A-F or WE54A-T6?
WE54A-F. Its weldability rates very good (75/100) against very good (70/100) for WE54A-T6.
