Precious Metal AWS BVPd-1-ANN vs AWS BVPd-1-CD
Precious Metal · AWS BVPd-1 temper comparison
AWS BVPd-1-ANN and AWS BVPd-1-CD are two conditions of the same precious metal grade, AWS BVPd-1: ANN (annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. AWS BVPd-1-CD is the stronger of the two: yield strength 900 MPa (131 ksi) against 250 MPa (36.3 ksi) for AWS BVPd-1-ANN, about 3.6 times as much; tensile strength follows at 1,000 MPa (145 ksi) vs 600 MPa (87 ksi). In exchange, AWS BVPd-1-ANN is the more ductile: elongation 20% versus 3% for AWS BVPd-1-CD, and AWS BVPd-1-CD is harder (285 HB vs 166 HB). AWS BVPd-1-ANN runs hotter in service (800°C vs 400°C continuous) and AWS BVPd-1-ANN conducts electricity better (5 % IACS vs 4.5 % IACS).
AWS BVPd-1-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
AWS BVPd-1-CDChoose it when strength drives the design.
AWS BVPd-1-ANN vs AWS BVPd-1-CD: 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.
