Precious Metal Ag145 vs BAg-1
Precious Metal · grade comparison
Precious Metal Ag145 and BAg-1 are both precious metal grades. Ag145 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 200 MPa (29 ksi) for BAg-1, about 70% more; tensile strength follows at 450 MPa (65.3 ksi) vs 414 MPa (60 ksi). Ag145 is harder — 105 HB against 90 HB for BAg-1 — which matters for wear surfaces and threads.
Ag145Choose it when strength drives the design, or when surface hardness matters.
Ag145 vs BAg-1: 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.

Ag145 vs BAg-1 — frequently asked
Is Ag145 stronger than BAg-1?
Yes. Ag145 has a typical yield strength of 340 MPa (49.3 ksi) against 200 MPa (29 ksi) for BAg-1 — about 70% more. Tensile strength is 450 MPa (65.3 ksi) vs 414 MPa (60 ksi).
Which is cheaper, Ag145 or BAg-1?
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, Ag145 or BAg-1?
Ag145, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for BAg-1; for welding the order is Ag145 first (poor, 20/100) then BAg-1 (poor, 15/100).
