Precious Metal 800 Silver-PH vs 800 Silver Spring
Precious Metal · 800 Silver temper comparison
800 Silver-PH and 800 Silver Spring are two conditions of the same precious metal grade, 800 Silver: PH (pre-hardened) versus Spring (spring hard). The chemistry is identical, so every difference below comes from the condition. 800 Silver-PH is the stronger of the two: yield strength 510 MPa (74 ksi) against 480 MPa (69.6 ksi) for 800 Silver Spring, about 6% more; tensile strength follows at 580 MPa (84.1 ksi) vs 520 MPa (75.4 ksi). 800 Silver-PH is the more ductile: elongation 4% versus 3% for 800 Silver Spring, and 800 Silver-PH is harder (175 HB vs 155 HB). 800 Silver-PH runs hotter in service (250°C vs 150°C continuous) and 800 Silver-PH conducts heat better (345 W/m·K vs 305 W/m·K).

800 Silver-PH vs 800 Silver Spring: 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.

800 Silver-PH vs 800 Silver Spring — frequently asked
Is 800 Silver-PH stronger than 800 Silver Spring?
Yes. 800 Silver-PH has a typical yield strength of 510 MPa (74 ksi) against 480 MPa (69.6 ksi) for 800 Silver Spring — about 6% more. Tensile strength is 580 MPa (84.1 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, PH or Spring?
Annealed is the default 800 Silver condition in the FabDigit quote flow (neither PH nor Spring). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which welds better, 800 Silver-PH or 800 Silver Spring?
800 Silver Spring. Its weldability rates fair (50/100) against fair (45/100) for 800 Silver-PH.
