Precious Metal Ag130 vs BAg-2a

Precious Metal · grade comparison

Precious Metal Ag130 and BAg-2a are both precious metal grades. Ag130 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 210 MPa (30.5 ksi) for BAg-2a, about 19% more. In exchange, BAg-2a is the more ductile: elongation 28% versus 25% for Ag130, and Ag130 is harder (110 HB vs 85 HB). Ag130 is lighter (8.7 g/cm³ vs 9.4 g/cm³ for BAg-2a) and Ag130 is stiffer (95 GPa vs 90 GPa).

Ag130Choose it when strength drives the design, or when weight is the constraint.

BAg-2aChoose it when the part is bent, formed or impact-loaded.

Ag130 vs BAg-2a — frequently asked

Is Ag130 stronger than BAg-2a?

Yes. Ag130 has a typical yield strength of 250 MPa (36.3 ksi) against 210 MPa (30.5 ksi) for BAg-2a — about 19% more. Tensile strength is 410 MPa (59.5 ksi) vs 400 MPa (58 ksi).

Which is cheaper, Ag130 or BAg-2a?

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, Ag130 or BAg-2a?

BAg-2a. Its weldability rates poor (20/100) against poor (15/100) for Ag130.
