Precious Metal BAg-1 vs BVAg-8
Precious Metal · grade comparison
Precious Metal BAg-1 and BVAg-8 are both precious metal grades. BAg-1 is the stronger of the two: yield strength 200 MPa (29 ksi) against 120 MPa (17.4 ksi) for BVAg-8, about 67% more; tensile strength follows at 414 MPa (60 ksi) vs 275 MPa (39.9 ksi). In exchange, BVAg-8 is the more ductile: elongation 25% versus 21% for BAg-1, and BAg-1 is harder (90 HB vs 60 HB). BAg-1 is lighter (9.3 g/cm³ vs 9.9 g/cm³ for BVAg-8) and BVAg-8 runs hotter in service (370°C vs 200°C continuous).
BAg-1Choose it when strength drives the design, or when weight is the constraint.
BVAg-8Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
BAg-1 vs BVAg-8: 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-1 vs BVAg-8 — frequently asked
Is BAg-1 stronger than BVAg-8?
Yes. BAg-1 has a typical yield strength of 200 MPa (29 ksi) against 120 MPa (17.4 ksi) for BVAg-8 — about 67% more. Tensile strength is 414 MPa (60 ksi) vs 275 MPa (39.9 ksi).
Which is cheaper, BAg-1 or BVAg-8?
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.
Which is easier to machine, BAg-1 or BVAg-8?
BAg-1, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for BVAg-8.
