Precious Metal BAg-2a vs PSr25

Precious Metal · grade comparison

Precious Metal BAg-2a and PSr25 are both precious metal grades. BAg-2a is the stronger of the two: tensile strength 400 MPa (58 ksi) against 350 MPa (50.8 ksi) for PSr25, about 14% more. BAg-2a is the more ductile: elongation 28% versus 20% for PSr25, and PSr25 is harder (95 HB vs 85 HB). PSr25 is lighter (8.7 g/cm³ vs 9.4 g/cm³ for BAg-2a) and PSr25 is stiffer (95 GPa vs 90 GPa).

BAg-2aChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

PSr25Choose it when weight is the constraint.

BAg-2a vs PSr25 — frequently asked

Is BAg-2a stronger than PSr25?

Yes. BAg-2a has a typical tensile strength of 400 MPa (58 ksi) against 350 MPa (50.8 ksi) for PSr25 — about 14% more.

Which is cheaper, BAg-2a or PSr25?

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 PSr25?

Pick BAg-2a when strength drives the design, or when the part is bent, formed or impact-loaded. Pick PSr25 when weight is the constraint.
