Precious Metal BAg-1 vs PSr45
Precious Metal · grade comparison
Precious Metal BAg-1 and PSr45 are both precious metal grades. Both yield at about 200 MPa — strength does not separate them. PSr45 is the more ductile: elongation 28% versus 21% for BAg-1.
PSr45Choose it when the part is bent, formed or impact-loaded.
BAg-1 vs PSr45: 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-1 vs PSr45 — frequently asked
What is the difference between BAg-1 and PSr45?
Precious Metal BAg-1 and PSr45 are both precious metal grades. Both yield at about 200 MPa — strength does not separate them. PSr45 is the more ductile: elongation 28% versus 21% for BAg-1.
Which is cheaper, BAg-1 or PSr45?
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 PSr45?
PSr45, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for BAg-1; for welding the order is PSr45 first (poor, 20/100) then BAg-1 (poor, 15/100).
