Precious Metal BAg-1 vs BAg15CuZnSn
Precious Metal · grade comparison
Precious Metal BAg-1 and BAg15CuZnSn are both precious metal grades. BAg15CuZnSn is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 200 MPa (29 ksi) for BAg-1, about 15% more. BAg15CuZnSn is harder — 105 HB against 90 HB for BAg-1 — which matters for wear surfaces and threads. BAg15CuZnSn is lighter (8.4 g/cm³ vs 9.3 g/cm³ for BAg-1) and BAg15CuZnSn is stiffer (95 GPa vs 83 GPa). On the shop floor, BAg15CuZnSn machines more easily (good vs fair) and BAg-1 forms better (very good vs good).
BAg15CuZnSnChoose it when strength drives the design, or when surface hardness matters.
BAg-1 vs BAg15CuZnSn: 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 BAg15CuZnSn — frequently asked
Is BAg15CuZnSn stronger than BAg-1?
Yes. BAg15CuZnSn has a typical yield strength of 230 MPa (33.4 ksi) against 200 MPa (29 ksi) for BAg-1 — about 15% more. Tensile strength is 400 MPa (58 ksi) vs 414 MPa (60 ksi).
Which is cheaper, BAg-1 or BAg15CuZnSn?
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 BAg15CuZnSn?
BAg15CuZnSn. Its machinability rates good (60/100) against fair (40/100) for BAg-1; for welding the order is BAg-1 first (poor, 15/100) then BAg15CuZnSn (not recommended, 10/100).
