Precious Metal Argentium 935 1/4H vs Argentium 935-O
Precious Metal · Argentium 935 temper comparison
Argentium 935 1/4H and Argentium 935-O are two conditions of the same precious metal grade, Argentium 935: 1/4H (quarter hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. Argentium 935 1/4H is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 80 MPa (11.6 ksi) for Argentium 935-O, about 175% more; tensile strength follows at 330 MPa (47.9 ksi) vs 260 MPa (37.7 ksi). In exchange, Argentium 935-O is the more ductile: elongation 45% versus 20% for Argentium 935 1/4H, and Argentium 935 1/4H is harder (72 HB vs 48 HB). Argentium 935-O runs hotter in service (200°C vs 180°C continuous).

Argentium 935-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Argentium 935 1/4H vs Argentium 935-O: 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.
