Precious Metal BAg-10 vs BAg-2a
Precious Metal · grade comparison
Precious Metal BAg-10 and BAg-2a are both precious metal grades. Both yield at about 200 MPa — strength does not separate them. BAg-2a is harder — 95 HV against 90 HV for BAg-10 — which matters for wear surfaces and threads. BAg-2a is lighter (9.4 g/cm³ vs 9.8 g/cm³ for BAg-10) and BAg-2a is stiffer (90 GPa vs 85 GPa). On the shop floor, BAg-10 machines more easily (good vs fair).
BAg-10Choose it when the part sees heat, or when the part is machined in volume.
BAg-2aChoose it when surface hardness matters, or when weight is the constraint.
BAg-10 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.

BAg-10 vs BAg-2a — frequently asked
What is the difference between BAg-10 and BAg-2a?
Precious Metal BAg-10 and BAg-2a are both precious metal grades. Both yield at about 200 MPa — strength does not separate them. BAg-2a is harder — 95 HV against 90 HV for BAg-10 — which matters for wear surfaces and threads.
Which is cheaper, BAg-10 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.
Which is easier to machine, BAg-10 or BAg-2a?
BAg-10. Its machinability rates good (55/100) against fair (45/100) for BAg-2a.
