Precious Metal BVAu-8-ANN vs BVAu-8 AS-BRAZED
Precious Metal · BVAu-8 temper comparison
BVAu-8-ANN and BVAu-8 AS-BRAZED are two conditions of the same precious metal grade, BVAu-8: ANN (annealed) versus AS-BRAZED. The chemistry is identical, so every difference below comes from the condition. BVAu-8-ANN is the stronger of the two: yield strength 100 MPa (14.5 ksi) against 95 MPa (13.8 ksi) for BVAu-8 AS-BRAZED, about 5% more. BVAu-8-ANN is the more ductile: elongation 30% versus 20% for BVAu-8 AS-BRAZED, and BVAu-8 AS-BRAZED is harder (62 HB vs 58 HB).
BVAu-8-ANNChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
BVAu-8-ANN vs BVAu-8 AS-BRAZED: 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.
