Precious Metal Pt950 As Cast vs Pt950 Cold Worked
Precious Metal · Pt950 temper comparison
Pt950 As Cast and Pt950 Cold Worked are two conditions of the same precious metal grade, Pt950: As Cast versus Cold Worked. The chemistry is identical, so every difference below comes from the condition. Pt950 Cold Worked is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 175 MPa (25.4 ksi) for Pt950 As Cast, about 3.2 times as much; tensile strength follows at 650 MPa (94.3 ksi) vs 350 MPa (50.8 ksi). In exchange, Pt950 As Cast is the more ductile: elongation 22% versus 3% for Pt950 Cold Worked, and Pt950 Cold Worked is harder (235 HB vs 124 HB). Pt950 As Cast runs hotter in service (1,200°C vs 400°C continuous). On the shop floor, Pt950 Cold Worked machines more easily (fair vs poor).
Pt950 As CastChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Pt950 Cold WorkedChoose it when strength drives the design, or when the part is machined in volume.
Pt950 As Cast vs Pt950 Cold Worked: 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.
