Magnesium Alloy AZ61A As Welded vs AZ61A-F
Magnesium Alloy · AZ61A temper comparison
AZ61A As Welded and AZ61A-F are two conditions of the same magnesium alloy grade, AZ61A: As Welded (as-welded deposit) versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. AZ61A-F is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 160 MPa (23.2 ksi) for AZ61A As Welded, about 44% more; tensile strength follows at 310 MPa (45 ksi) vs 250 MPa (36.3 ksi). AZ61A-F is the more ductile: elongation 16% versus 8% for AZ61A As Welded, and AZ61A-F is harder (60 HB vs 55 HB).
AZ61A-FChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
AZ61A As Welded vs AZ61A-F: 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.

AZ61A As Welded vs AZ61A-F — frequently asked
Is AZ61A-F stronger than AZ61A As Welded?
Yes. AZ61A-F has a typical yield strength of 230 MPa (33.4 ksi) against 160 MPa (23.2 ksi) for AZ61A As Welded — about 44% more. Tensile strength is 310 MPa (45 ksi) vs 250 MPa (36.3 ksi).
Which condition does FabDigit quote by default, As Welded or F?
F is the default AZ61A 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, AZ61A As Welded or AZ61A-F?
AZ61A As Welded. Its weldability rates very good (75/100) against very good (70/100) for AZ61A-F.
