Precious Metal BAg-9-AB vs BAg-9-ANN
Precious Metal · BAg-9 temper comparison
BAg-9-AB and BAg-9-ANN are two conditions of the same precious metal grade, BAg-9: AB (as built (as printed)) versus ANN (annealed). The chemistry is identical, so every difference below comes from the condition. BAg-9-ANN is the stronger of the two: yield strength 170 MPa (24.7 ksi) against 150 MPa (21.8 ksi) for BAg-9-AB, about 13% more; tensile strength follows at 380 MPa (55.1 ksi) vs 340 MPa (49.3 ksi). BAg-9-ANN is the more ductile: elongation 32% versus 25% for BAg-9-AB, and BAg-9-ANN is harder (85 HB vs 80 HB).
BAg-9-ANNChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
BAg-9-AB vs BAg-9-ANN: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all precious metal 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.

BAg-9-AB vs BAg-9-ANN — frequently asked
Is BAg-9-ANN stronger than BAg-9-AB?
Yes. BAg-9-ANN has a typical yield strength of 170 MPa (24.7 ksi) against 150 MPa (21.8 ksi) for BAg-9-AB — about 13% more. Tensile strength is 380 MPa (55.1 ksi) vs 340 MPa (49.3 ksi).
Which condition does FabDigit quote by default, AB or ANN?
ANN is the default BAg-9 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, BAg-9-AB or BAg-9-ANN?
BAg-9-ANN. Its weldability rates poor (30/100) against poor (25/100) for BAg-9-AB.
