Magnesium Alloy AZ80A As Extruded vs AZ80A-T5
Magnesium Alloy · AZ80A temper comparison
AZ80A As Extruded and AZ80A-T5 are two conditions of the same magnesium alloy grade, AZ80A: As Extruded (extruded bar, rod, tube and shapes) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. AZ80A-T5 is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 250 MPa (36.3 ksi) for AZ80A As Extruded, about 10% more; tensile strength follows at 380 MPa (55.1 ksi) vs 340 MPa (49.3 ksi). In exchange, AZ80A As Extruded is the more ductile: elongation 11% versus 7% for AZ80A-T5, and AZ80A-T5 is harder (72 HB vs 60 HB).
AZ80A As ExtrudedChoose it when the part is bent, formed or impact-loaded.
AZ80A-T5Choose it when strength drives the design.
AZ80A As Extruded vs AZ80A-T5: 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-T5 — frequently asked
Is AZ80A-T5 stronger than AZ80A As Extruded?
Yes. AZ80A-T5 has a typical yield strength of 275 MPa (39.9 ksi) against 250 MPa (36.3 ksi) for AZ80A As Extruded — about 10% more. Tensile strength is 380 MPa (55.1 ksi) vs 340 MPa (49.3 ksi).
Which condition does FabDigit quote by default, As Extruded or T5?
F is the default AZ80A condition in the FabDigit quote flow (neither As Extruded nor T5). 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 AZ80A As Extruded over AZ80A-T5?
Pick AZ80A As Extruded when the part is bent, formed or impact-loaded. Pick AZ80A-T5 when strength drives the design.
