Precious Metal BAg-2a vs BVAg-29
Precious Metal · grade comparison
Precious Metal BAg-2a and BVAg-29 are both precious metal grades. BAg-2a is the stronger of the two: yield strength 210 MPa (30.5 ksi) against 150 MPa (21.8 ksi) for BVAg-29, about 40% more; tensile strength follows at 400 MPa (58 ksi) vs 255 MPa (37 ksi). BAg-2a is the more ductile: elongation 28% versus 22% for BVAg-29, and BAg-2a is harder (95 HV vs 90 HV). BAg-2a is lighter (9.4 g/cm³ vs 9.7 g/cm³ for BVAg-29) and BAg-2a is stiffer (90 GPa vs 83 GPa).
BAg-2aChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
BVAg-29Choose it when the part sees heat.
BAg-2a vs BVAg-29: 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-2a vs BVAg-29 — frequently asked
Is BAg-2a stronger than BVAg-29?
Yes. BAg-2a has a typical yield strength of 210 MPa (30.5 ksi) against 150 MPa (21.8 ksi) for BVAg-29 — about 40% more. Tensile strength is 400 MPa (58 ksi) vs 255 MPa (37 ksi).
Which is cheaper, BAg-2a or BVAg-29?
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 BAg-2a over BVAg-29?
Pick BAg-2a when strength drives the design, or when the part is bent, formed or impact-loaded. Pick BVAg-29 when the part sees heat.
