Precious Metal AgNi10 vs Silver 999

Precious Metal · grade comparison

Precious Metal AgNi10 and Silver 999 are both precious metal grades. AgNi10 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 55 MPa (7.98 ksi) for Silver 999, about 64% more; tensile strength follows at 230 MPa (33.4 ksi) vs 140 MPa (20.3 ksi). In exchange, Silver 999 is the more ductile: elongation 48% versus 25% for AgNi10, and AgNi10 is harder (58 HB vs 25 HB). AgNi10 is stiffer (90 GPa vs 76 GPa) and Silver 999 runs hotter in service (250°C vs 200°C continuous). On the shop floor, AgNi10 machines more easily (good vs fair), AgNi10 welds better (very good vs good), and AgNi10 sits in a lower cost tier (high, $$$$) than Silver 999 (specialty, $$$$$).

AgNi10Choose it when strength drives the design, or when the part is machined in volume.

Silver 999Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
