Precious Metal Ag149 vs BAg-13a
Precious Metal · grade comparison
Precious Metal Ag149 and BAg-13a are both precious metal grades. Ag149 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 210 MPa (30.5 ksi) for BAg-13a, about 43% more; tensile strength follows at 500 MPa (72.5 ksi) vs 420 MPa (60.9 ksi). Ag149 is the more ductile: elongation 25% versus 22% for BAg-13a, and Ag149 is harder (125 HB vs 100 HB). Ag149 is lighter (9 g/cm³ vs 9.75 g/cm³ for BAg-13a) and BAg-13a is stiffer (95 GPa vs 85 GPa).
Ag149Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Ag149 vs BAg-13a: 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.

Ag149 vs BAg-13a — frequently asked
Is Ag149 stronger than BAg-13a?
Yes. Ag149 has a typical yield strength of 300 MPa (43.5 ksi) against 210 MPa (30.5 ksi) for BAg-13a — about 43% more. Tensile strength is 500 MPa (72.5 ksi) vs 420 MPa (60.9 ksi).
Which is cheaper, Ag149 or BAg-13a?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose Ag149 over BAg-13a?
Pick Ag149 when strength drives the design, or when the part is bent, formed or impact-loaded.
