Precious Metal Ag145 vs BAg-2a
Precious Metal · grade comparison
Precious Metal Ag145 and BAg-2a are both precious metal grades. Ag145 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 210 MPa (30.5 ksi) for BAg-2a, about 62% more; tensile strength follows at 450 MPa (65.3 ksi) vs 400 MPa (58 ksi). In exchange, BAg-2a is the more ductile: elongation 28% versus 20% for Ag145, and Ag145 is harder (105 HB vs 85 HB). Ag145 is lighter (9.1 g/cm³ vs 9.4 g/cm³ for BAg-2a) and BAg-2a is stiffer (90 GPa vs 85 GPa).
Ag145Choose it when strength drives the design, or when weight is the constraint.
BAg-2aChoose it when the part is bent, formed or impact-loaded.
Ag145 vs BAg-2a: 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.

Ag145 vs BAg-2a — frequently asked
Is Ag145 stronger than BAg-2a?
Yes. Ag145 has a typical yield strength of 340 MPa (49.3 ksi) against 210 MPa (30.5 ksi) for BAg-2a — about 62% more. Tensile strength is 450 MPa (65.3 ksi) vs 400 MPa (58 ksi).
Which is cheaper, Ag145 or BAg-2a?
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 Ag145 over BAg-2a?
Pick Ag145 when strength drives the design, or when weight is the constraint. Pick BAg-2a when the part is bent, formed or impact-loaded.
