Precious Metal BAg-5 vs Coin Silver 900
Precious Metal · grade comparison
Precious Metal BAg-5 and Coin Silver 900 are both precious metal grades. BAg-5 is the stronger of the two: yield strength 200 MPa (29 ksi) against 100 MPa (14.5 ksi) for Coin Silver 900, about 100% more; tensile strength follows at 415 MPa (60.2 ksi) vs 290 MPa (42.1 ksi). In exchange, Coin Silver 900 is the more ductile: elongation 40% versus 28% for BAg-5, and BAg-5 is harder (100 HB vs 66 HB). BAg-5 is lighter (9.1 g/cm³ vs 10.31 g/cm³ for Coin Silver 900) and BAg-5 is stiffer (85 GPa vs 78 GPa). On the shop floor, BAg-5 machines more easily (good vs fair).
BAg-5Choose it when strength drives the design, or when weight is the constraint.
Coin Silver 900Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
BAg-5 vs Coin Silver 900: 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-5 vs Coin Silver 900 — frequently asked
Is BAg-5 stronger than Coin Silver 900?
Yes. BAg-5 has a typical yield strength of 200 MPa (29 ksi) against 100 MPa (14.5 ksi) for Coin Silver 900 — about 100% more. Tensile strength is 415 MPa (60.2 ksi) vs 290 MPa (42.1 ksi).
Which is cheaper, BAg-5 or Coin Silver 900?
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-5 or Coin Silver 900?
BAg-5. Its machinability rates good (55/100) against fair (40/100) for Coin Silver 900.
