Precious Metal BAg-24 vs BAg-2a
Precious Metal · grade comparison
Precious Metal BAg-24 and BAg-2a are both precious metal grades. BAg-24 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 210 MPa (30.5 ksi) for BAg-2a, about 19% more. BAg-2a is stiffer (90 GPa vs 85 GPa) and BAg-24 runs hotter in service (300°C vs 200°C continuous).
BAg-24Choose it when strength drives the design, or when the part sees heat.
BAg-24 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-24 vs BAg-2a — frequently asked
Is BAg-24 stronger than BAg-2a?
Yes. BAg-24 has a typical yield strength of 250 MPa (36.3 ksi) against 210 MPa (30.5 ksi) for BAg-2a — about 19% more. Tensile strength is 420 MPa (60.9 ksi) vs 400 MPa (58 ksi).
Which is cheaper, BAg-24 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 BAg-24 over BAg-2a?
Pick BAg-24 when strength drives the design, or when the part sees heat.
