Precious Metal BAg-1 vs PSr25

Precious Metal · grade comparison

Precious Metal BAg-1 and PSr25 are both precious metal grades. BAg-1 is the stronger of the two: tensile strength 414 MPa (60 ksi) against 350 MPa (50.8 ksi) for PSr25, about 18% more. PSr25 is harder — 95 HB against 90 HB for BAg-1 — which matters for wear surfaces and threads. PSr25 is lighter (8.7 g/cm³ vs 9.3 g/cm³ for BAg-1) and PSr25 is stiffer (95 GPa vs 83 GPa).

BAg-1Choose it when strength drives the design.

PSr25Choose it when surface hardness matters, or when weight is the constraint.

BAg-1 vs PSr25 — frequently asked

Is BAg-1 stronger than PSr25?

Yes. BAg-1 has a typical tensile strength of 414 MPa (60 ksi) against 350 MPa (50.8 ksi) for PSr25 — about 18% more.

Which is cheaper, BAg-1 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.

Which is easier to machine, BAg-1 or PSr25?

PSr25, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for BAg-1; for welding the order is PSr25 first (poor, 20/100) then BAg-1 (poor, 15/100).
