Precious Metal BAg-1 vs BAg-9

Precious Metal · grade comparison

Precious Metal BAg-1 and BAg-9 are both precious metal grades. BAg-1 is the stronger of the two: yield strength 200 MPa (29 ksi) against 170 MPa (24.7 ksi) for BAg-9, about 18% more; tensile strength follows at 414 MPa (60 ksi) vs 380 MPa (55.1 ksi). In exchange, BAg-9 is the more ductile: elongation 32% versus 21% for BAg-1, and BAg-1 is harder (90 HB vs 85 HB). BAg-1 is lighter (9.3 g/cm³ vs 9.8 g/cm³ for BAg-9). On the shop floor, BAg-9 welds better (30 vs 15 out of 100).

BAg-1Choose it when strength drives the design, or when weight is the constraint.

BAg-9Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

BAg-1 vs BAg-9 — frequently asked

Is BAg-1 stronger than BAg-9?

Yes. BAg-1 has a typical yield strength of 200 MPa (29 ksi) against 170 MPa (24.7 ksi) for BAg-9 — about 18% more. Tensile strength is 414 MPa (60 ksi) vs 380 MPa (55.1 ksi).

Which is cheaper, BAg-1 or BAg-9?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which welds better, BAg-1 or BAg-9?

BAg-9. Its weldability rates poor (30/100) against poor (15/100) for BAg-1.
