Magnesium Alloy AZ80A As Extruded vs AZ80A-T6
Magnesium Alloy · AZ80A temper comparison
AZ80A As Extruded and AZ80A-T6 are two conditions of the same magnesium alloy grade, AZ80A: As Extruded (extruded bar, rod, tube and shapes) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. Both yield at about 250 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (extruded bar, rod, tube and shapes versus solution heat treated and artificially aged). AZ80A As Extruded is the more ductile: elongation 11% versus 5% for AZ80A-T6, and AZ80A-T6 is harder (70 HB vs 60 HB).

AZ80A As Extruded vs AZ80A-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.

AZ80A As Extruded vs AZ80A-T6 — frequently asked
What is the difference between AZ80A As Extruded and AZ80A-T6?
AZ80A As Extruded and AZ80A-T6 are two conditions of the same magnesium alloy grade, AZ80A: As Extruded (extruded bar, rod, tube and shapes) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. Both yield at about 250 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (extruded bar, rod, tube and shapes versus solution heat treated and artificially aged).
Which condition does FabDigit quote by default, As Extruded or T6?
F is the default AZ80A condition in the FabDigit quote flow (neither As Extruded nor T6). 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, AZ80A As Extruded or AZ80A-T6?
AZ80A As Extruded. Its weldability rates fair (45/100) against fair (40/100) for AZ80A-T6.
