Product Description


Pure silver wire is made from 99.9% pure silver (Ag) and is renowned for its excellent electrical conductivity, high thermal conductivity, and resistance to corrosion. It is soft, highly ductile, and can be easily formed into various wire gauges and configurations. Pure silver wire is widely used in industries ranging from electronics to jewelry due to its superior physical and electrical properties.
Silver’s conductivity is second only to copper, which makes it an ideal material for a variety of applications where efficient current transmission and minimal energy loss are required. However, unlike copper, silver is more resistant to corrosion and tarnishing, especially when it is in its pure form.


Key Features & Advantages

Excellent Electrical Conductivity:

Pure silver wire boasts the highest electrical conductivity of any metal, making it ideal for electrical and electronic applications.

Superior Thermal Conductivity:

Silver's excellent heat conductivity makes it highly effective in systems that require quick dissipation of heat.

Corrosion Resistance:

Pure silver is highly resistant to corrosion and tarnishing, which ensures its longevity in various environments.

Malleability and Ductility:

Silver is a very ductile metal, meaning it can be easily drawn into very thin wires without breaking.

Low Contact Resistance

Pure silver wire ensures minimal energy loss in electrical connections and is particularly effective in high-frequency applications.

Bio-compatibility:

Silver is bio-compatible and is used in medical devices and implants, making it ideal for applications in the medical industry.

Aesthetic Appeal

Its bright, shiny appearance makes pure silver wire desirable in jewelry, decorative items, and other aesthetic applications.
