Precious Metal BAg-9-ANN vs BAg-9 Hard

Precious Metal · BAg-9 temper comparison

BAg-9-ANN and BAg-9 Hard are two conditions of the same precious metal grade, BAg-9: ANN (annealed) versus Hard (cold drawn / hard temper wire and strip). The chemistry is identical, so every difference below comes from the condition. BAg-9 Hard is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 170 MPa (24.7 ksi) for BAg-9-ANN, about 3.1 times as much; tensile strength follows at 620 MPa (89.9 ksi) vs 380 MPa (55.1 ksi). In exchange, BAg-9-ANN is the more ductile: elongation 32% versus 4% for BAg-9 Hard, and BAg-9 Hard is harder (155 HB vs 85 HB). BAg-9-ANN runs hotter in service (200°C vs 150°C continuous). On the shop floor, BAg-9 Hard machines more easily (50 vs 40 out of 100).

BAg-9-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

BAg-9 HardChoose it when strength drives the design, or when the part is machined in volume.

BAg-9-ANN vs BAg-9 Hard — frequently asked

Is BAg-9 Hard stronger than BAg-9-ANN?

Yes. BAg-9 Hard has a typical yield strength of 520 MPa (75.4 ksi) against 170 MPa (24.7 ksi) for BAg-9-ANN — about 3.1 times as much. Tensile strength is 620 MPa (89.9 ksi) vs 380 MPa (55.1 ksi).

Which condition does FabDigit quote by default, ANN or Hard?

ANN is the default BAg-9 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-9-ANN or BAg-9 Hard?

BAg-9 Hard, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for BAg-9-ANN.
