Precious Metal 800 Silver 1/4H vs 800 Silver-PH
Precious Metal · 800 Silver temper comparison
800 Silver 1/4H and 800 Silver-PH are two conditions of the same precious metal grade, 800 Silver: 1/4H (quarter hard) versus PH (pre-hardened). 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 250 MPa (36.3 ksi) for 800 Silver 1/4H, about 104% more; tensile strength follows at 580 MPa (84.1 ksi) vs 350 MPa (50.8 ksi). In exchange, 800 Silver 1/4H is the more ductile: elongation 20% versus 4% for 800 Silver-PH, and 800 Silver-PH is harder (175 HB vs 100 HB). 800 Silver-PH runs hotter in service (250°C vs 200°C continuous). On the shop floor, 800 Silver-PH machines more easily (good vs fair) and 800 Silver 1/4H welds better (good vs fair).
800 Silver 1/4HChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
800 Silver-PHChoose it when strength drives the design, or when the part sees heat.
800 Silver 1/4H vs 800 Silver-PH: 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 1/4H vs 800 Silver-PH — frequently asked
Is 800 Silver-PH stronger than 800 Silver 1/4H?
Yes. 800 Silver-PH has a typical yield strength of 510 MPa (74 ksi) against 250 MPa (36.3 ksi) for 800 Silver 1/4H — about 104% more. Tensile strength is 580 MPa (84.1 ksi) vs 350 MPa (50.8 ksi).
Which condition does FabDigit quote by default, 1/4H or PH?
Annealed is the default 800 Silver condition in the FabDigit quote flow (neither 1/4H nor PH). 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 is easier to machine, 800 Silver 1/4H or 800 Silver-PH?
800 Silver-PH. Its machinability rates good (65/100) against fair (52/100) for 800 Silver 1/4H; for welding the order is 800 Silver 1/4H first (good, 65/100) then 800 Silver-PH (fair, 45/100).
