Precious Metal BAg-8 Annealed vs BAg-8 Hard
Precious Metal · BAg-8 temper comparison
BAg-8 Annealed and BAg-8 Hard are two conditions of the same precious metal grade, BAg-8: Annealed versus Hard (hard drawn). The chemistry is identical, so every difference below comes from the condition. BAg-8 Hard is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 160 MPa (23.2 ksi) for BAg-8 Annealed, about 3.0 times as much; tensile strength follows at 620 MPa (89.9 ksi) vs 380 MPa (55.1 ksi). In exchange, BAg-8 Annealed is the more ductile: elongation 20% versus 4% for BAg-8 Hard, and BAg-8 Hard is harder (130 HB vs 65 HB). BAg-8 Annealed runs hotter in service (400°C vs 200°C continuous). On the shop floor, BAg-8 Hard machines more easily (65 vs 55 out of 100).
BAg-8 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
BAg-8 HardChoose it when strength drives the design, or when the part is machined in volume.
BAg-8 Annealed vs BAg-8 Hard: 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.

BAg-8 Annealed vs BAg-8 Hard — frequently asked
Is BAg-8 Hard stronger than BAg-8 Annealed?
Yes. BAg-8 Hard has a typical yield strength of 480 MPa (69.6 ksi) against 160 MPa (23.2 ksi) for BAg-8 Annealed — about 3.0 times as much. Tensile strength is 620 MPa (89.9 ksi) vs 380 MPa (55.1 ksi).
Which condition does FabDigit quote by default, Annealed or Hard?
Annealed is the default BAg-8 condition in the FabDigit quote flow. 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, BAg-8 Annealed or BAg-8 Hard?
BAg-8 Hard, by a small margin. Both rate good for machinability — 65/100 against 55/100 for BAg-8 Annealed.
