Precious Metal 950 Silver (Minerve) vs Coin Silver 900
Precious Metal · grade comparison
Precious Metal 950 Silver (Minerve) and Coin Silver 900 are both precious metal grades. Coin Silver 900 is the stronger of the two: yield strength 100 MPa (14.5 ksi) against 65 MPa (9.43 ksi) for 950 Silver (Minerve), about 54% more; tensile strength follows at 290 MPa (42.1 ksi) vs 250 MPa (36.3 ksi). In exchange, 950 Silver (Minerve) is the more ductile: elongation 45% versus 40% for Coin Silver 900, and Coin Silver 900 is harder (66 HB vs 52 HB). Coin Silver 900 runs hotter in service (250°C vs 200°C continuous) and 950 Silver (Minerve) conducts heat better (380 W/m·K vs 330 W/m·K). On the shop floor, 950 Silver (Minerve) machines more easily (good vs fair) and 950 Silver (Minerve) welds better (very good vs good).
950 Silver (Minerve)Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Coin Silver 900Choose it when strength drives the design, or when the part sees heat.
950 Silver (Minerve) vs Coin Silver 900: 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.
