Precious Metal AWS BVPd-1 vs Silver 999
Precious Metal · grade comparison
Precious Metal AWS BVPd-1 and Silver 999 are both precious metal grades. AWS BVPd-1 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 55 MPa (7.98 ksi) for Silver 999, about 6.9 times as much; tensile strength follows at 620 MPa (89.9 ksi) vs 140 MPa (20.3 ksi). In exchange, Silver 999 is the more ductile: elongation 48% versus 15% for AWS BVPd-1, and AWS BVPd-1 is harder (190 HB vs 25 HB). AWS BVPd-1 is stiffer (150 GPa vs 76 GPa) and AWS BVPd-1 runs hotter in service (800°C vs 250°C continuous). On the shop floor, Silver 999 machines more easily (fair vs poor) and AWS BVPd-1 sits in a lower cost tier (high, $$$$) than Silver 999 (specialty, $$$$$).
AWS BVPd-1Choose it when strength drives the design, or when the part sees heat.
Silver 999Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
AWS BVPd-1 vs Silver 999: 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.
