Precious Metal 833 Silver vs Coin Silver 900
Precious Metal · grade comparison
Precious Metal 833 Silver and Coin Silver 900 are both precious metal grades. Both yield at about 100 MPa — strength does not separate them. Coin Silver 900 is harder — 66 HB against 58 HB for 833 Silver — which matters for wear surfaces and threads. On the shop floor, 833 Silver machines more easily (50 vs 40 out of 100).

833 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.

833 Silver vs Coin Silver 900 — frequently asked
What is the difference between 833 Silver and Coin Silver 900?
Precious Metal 833 Silver and Coin Silver 900 are both precious metal grades. Both yield at about 100 MPa — strength does not separate them. Coin Silver 900 is harder — 66 HB against 58 HB for 833 Silver — which matters for wear surfaces and threads.
Which is cheaper, 833 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, 833 Silver or Coin Silver 900?
833 Silver, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for Coin Silver 900; for welding the order is 833 Silver first (good, 60/100) then Coin Silver 900 (good, 55/100).
