Precious Metal 830 Silver vs Coin Silver 900
Precious Metal · grade comparison
Precious Metal 830 Silver and Coin Silver 900 are both precious metal grades. Both yield at about 105 MPa — strength does not separate them. Coin Silver 900 is harder — 66 HB against 62 HB for 830 Silver — which matters for wear surfaces and threads. 830 Silver runs hotter in service (300°C vs 250°C continuous). On the shop floor, 830 Silver machines more easily (good vs fair) and 830 Silver welds better (very good vs good).
830 SilverChoose it when the part sees heat, or when the part is machined in volume.
Coin Silver 900Choose it when surface hardness matters.
830 Silver 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.

830 Silver vs Coin Silver 900 — frequently asked
What is the difference between 830 Silver and Coin Silver 900?
Precious Metal 830 Silver and Coin Silver 900 are both precious metal grades. Both yield at about 105 MPa — strength does not separate them. Coin Silver 900 is harder — 66 HB against 62 HB for 830 Silver — which matters for wear surfaces and threads.
Which is cheaper, 830 Silver or Coin Silver 900?
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, 830 Silver or Coin Silver 900?
830 Silver. Its machinability rates good (55/100) against fair (40/100) for Coin Silver 900; for welding the order is 830 Silver first (very good, 70/100) then Coin Silver 900 (good, 55/100).
