835 Silver vs Coin Silver 900 — frequently asked

Is 835 Silver stronger than Coin Silver 900?

Yes. 835 Silver has a typical yield strength of 110 MPa (16 ksi) against 100 MPa (14.5 ksi) for Coin Silver 900 — about 10% more. Tensile strength is 300 MPa (43.5 ksi) vs 290 MPa (42.1 ksi).

Which is cheaper, 835 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, 835 Silver or Coin Silver 900?

835 Silver, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for Coin Silver 900; for welding the order is 835 Silver first (good, 60/100) then Coin Silver 900 (good, 55/100).
