Magnesium Alloy WE54 EXT-T5 vs WE54-T6
Magnesium Alloy · WE54 temper comparison
WE54 EXT-T5 and WE54-T6 are two conditions of the same magnesium alloy grade, WE54: EXT-T5 (extruded / forged and aged) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. WE54 EXT-T5 is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 200 MPa (29 ksi) for WE54-T6, about 10% more; tensile strength follows at 310 MPa (45 ksi) vs 270 MPa (39.2 ksi). WE54 EXT-T5 is the more ductile: elongation 8% versus 4% for WE54-T6, and WE54 EXT-T5 is harder (90 HB vs 85 HB).
WE54 EXT-T5Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
WE54 EXT-T5 vs WE54-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.

WE54 EXT-T5 vs WE54-T6 — frequently asked
Is WE54 EXT-T5 stronger than WE54-T6?
Yes. WE54 EXT-T5 has a typical yield strength of 220 MPa (31.9 ksi) against 200 MPa (29 ksi) for WE54-T6 — about 10% more. Tensile strength is 310 MPa (45 ksi) vs 270 MPa (39.2 ksi).
Which condition does FabDigit quote by default, EXT-T5 or T6?
T6 is the default WE54 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 WE54 EXT-T5 over WE54-T6?
Pick WE54 EXT-T5 when strength drives the design, or when the part is bent, formed or impact-loaded.
