Magnesium Alloy AWS BMg-1 AS-WELDED vs AWS BMg-1-F
Magnesium Alloy · AWS BMg-1 temper comparison
AWS BMg-1 AS-WELDED and AWS BMg-1-F are two conditions of the same magnesium alloy grade, AWS BMg-1: AS-WELDED (as-welded deposit) versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. AWS BMg-1-F is the stronger of the two: yield strength 140 MPa (20.3 ksi) against 110 MPa (16 ksi) for AWS BMg-1 AS-WELDED, about 27% more; tensile strength follows at 230 MPa (33.4 ksi) vs 200 MPa (29 ksi). AWS BMg-1-F is the more ductile: elongation 6% versus 4% for AWS BMg-1 AS-WELDED, and AWS BMg-1-F is harder (72 HV vs 68 HV). AWS BMg-1-F conducts heat better (79 W/m·K vs 70 W/m·K). On the shop floor, AWS BMg-1-F welds better (very good vs good).
AWS BMg-1-FChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
AWS BMg-1 AS-WELDED vs AWS BMg-1-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.

AWS BMg-1 AS-WELDED vs AWS BMg-1-F — frequently asked
Is AWS BMg-1-F stronger than AWS BMg-1 AS-WELDED?
Yes. AWS BMg-1-F has a typical yield strength of 140 MPa (20.3 ksi) against 110 MPa (16 ksi) for AWS BMg-1 AS-WELDED — about 27% more. Tensile strength is 230 MPa (33.4 ksi) vs 200 MPa (29 ksi).
Which condition does FabDigit quote by default, AS-WELDED or F?
AS-BRAZED is the default AWS BMg-1 condition in the FabDigit quote flow (neither AS-WELDED nor F). 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, AWS BMg-1 AS-WELDED or AWS BMg-1-F?
AWS BMg-1-F. Its weldability rates very good (70/100) against good (60/100) for AWS BMg-1 AS-WELDED.
