Precious Metal Ag149 vs BAg-1

Precious Metal · grade comparison

Precious Metal Ag149 and BAg-1 are both precious metal grades. Ag149 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 200 MPa (29 ksi) for BAg-1, about 50% more; tensile strength follows at 500 MPa (72.5 ksi) vs 414 MPa (60 ksi). Ag149 is the more ductile: elongation 25% versus 21% for BAg-1, and Ag149 is harder (125 HB vs 90 HB). Ag149 is lighter (9 g/cm³ vs 9.3 g/cm³ for BAg-1) and Ag149 runs hotter in service (400°C vs 200°C continuous).

Ag149Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

Ag149 vs BAg-1 — frequently asked

Is Ag149 stronger than BAg-1?

Yes. Ag149 has a typical yield strength of 300 MPa (43.5 ksi) against 200 MPa (29 ksi) for BAg-1 — about 50% more. Tensile strength is 500 MPa (72.5 ksi) vs 414 MPa (60 ksi).

Which is cheaper, Ag149 or BAg-1?

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.

When should I choose Ag149 over BAg-1?

Pick Ag149 when strength drives the design, or when the part is bent, formed or impact-loaded.
