Magnesium Alloy WE54A-T5 vs WE54A-T6
Magnesium Alloy · WE54A temper comparison
WE54A-T5 and WE54A-T6 are two conditions of the same magnesium alloy grade, WE54A: T5 (cooled from hot working and artificially aged) 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 160 MPa (23.2 ksi) for WE54A-T5, about 19% more; tensile strength follows at 275 MPa (39.9 ksi) vs 235 MPa (34.1 ksi). WE54A-T6 is the more ductile: elongation 4% versus 3% for WE54A-T5, and WE54A-T6 is harder (85 HB vs 75 HB).
WE54A-T6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
WE54A-T5 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-T5 vs WE54A-T6 — frequently asked
Is WE54A-T6 stronger than WE54A-T5?
Yes. WE54A-T6 has a typical yield strength of 190 MPa (27.6 ksi) against 160 MPa (23.2 ksi) for WE54A-T5 — about 19% more. Tensile strength is 275 MPa (39.9 ksi) vs 235 MPa (34.1 ksi).
Which condition does FabDigit quote by default, T5 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.
When should I choose WE54A-T5 over WE54A-T6?
Pick WE54A-T6 when strength drives the design, or when the part is bent, formed or impact-loaded.
