Formula: Ag 92.5/Cu 7.5
Form: Foil/Film/Sheet
Material: Silver/Copper (Sterling Silver)
Commodity: Precious Metals
Temper:
As Rolled
Thickness:
0.5mm
Sterling Silver Foil (Ag92.5/Cu7.5) combines high electrical conductivity, reflectivity, and malleability with the strength enhancement provided by copper alloying. In thin sheet form, it is used in precision electrical contacts, decorative elements, and optical components. Industries apply it in high-conductivity connectors, precision reflective surfaces, and fine metal laminates for jewelry and instrumentation. Specific applications include switch contacts in high-reliability circuits, decorative inlays requiring ductility and tarnish resistance, and precision reflective films in optical devices. In research, sterling silver foil is used to study alloy corrosion mechanisms, evaluate electrical performance under microfabrication, and develop thin-film composite materials. Its combination of formability, conductivity, and aesthetic quality ensures its value across electronics, optics, and applied materials science.
