Precious Metal Argentium 935 vs S800
Precious Metal · grade comparison
Precious Metal Argentium 935 and S800 are both precious metal grades. S800 is the stronger of the two: yield strength 110 MPa (16 ksi) against 80 MPa (11.6 ksi) for Argentium 935, about 38% more; tensile strength follows at 310 MPa (45 ksi) vs 260 MPa (37.7 ksi). In exchange, Argentium 935 is the more ductile: elongation 45% versus 35% for S800, and S800 is harder (66 HB vs 48 HB). S800 is stiffer (80 GPa vs 76 GPa) and Argentium 935 conducts electricity better (80 % IACS vs 60 % IACS). On the shop floor, Argentium 935 welds better (excellent vs good).
Argentium 935Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
S800Choose it when strength drives the design.
Argentium 935 vs S800: 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.

Argentium 935 vs S800 — frequently asked
Is S800 stronger than Argentium 935?
Yes. S800 has a typical yield strength of 110 MPa (16 ksi) against 80 MPa (11.6 ksi) for Argentium 935 — about 38% more. Tensile strength is 310 MPa (45 ksi) vs 260 MPa (37.7 ksi).
Which is cheaper, Argentium 935 or S800?
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, Argentium 935 or S800?
Argentium 935. Its machinability rates good (55/100) against fair (50/100) for S800; for welding the order is Argentium 935 first (excellent, 90/100) then S800 (good, 60/100).
