Metal Foil Sheet/Expanded Metal Mesh
Silver expanded mesh, silver diamond mesh, silver electrode, Ag expanded metal mesh, is an unique and specialized mesh type made from pure silver or silver alloys. It is less common than other types of expanded metal mesh made from stainless steel or aluminum, but it is used in specific applications where silver’s properties—such as its conductivity, corrosion resistance, and aesthetic appeal—are required.

Excellent Electrical Conductivity: Silver, the Precious metal. This is the primary reason for using pure silver in many technical applications.
Superb Thermal Conductivity: Also the high of any metal.
Antimicrobial: Silver ions are known to kill bacteria and microbes, making the pure silver expanded mesh useful in biotech and medical filters.
High Corrosion Resistance: Resists oxidation, though it will tarnish (form a layer of silver sulfide) when exposed to sulfur compounds in the air.
Soft and Malleable: Pure silver is very soft. This makes the silver expanded metal mesh less durable mechanically than its steel or aluminum counterparts and more susceptible to deformation.
The use of pure 99.99% stering Ag silver expanded mesh is almost exclusively in high-end, technical, and specialized fields:
Electronics & Electromagnetics:
EMI/RFI Shielding: Used as a gasket or screen to block electromagnetic or radio frequency interference in sensitive electronic equipment. Its high conductivity makes it extremely effective.
Battery Contacts & Electrodes: Especially in some high-performance or specialized battery and capacitor designs.
RF (Radio Frequency) Components: Used in waveguides or other components where superior surface conductivity is critical.
Catalysis & Chemical Processing:
Catalyst Substrate: Pure silver is a catalyst for several important chemical reactions, most notably the production of ethylene oxide from ethylene. The expanded mesh form provides a high surface area for the reaction to occur.
Filtration:
High-Purity Fluid Filters: Used in processes where absolute purity is essential, and silver’s inertness is beneficial (e.g., in pharmaceutical or fine chemical manufacturing).
Antimicrobial Filters: For air or liquid systems where preventing microbial growth is a critical requirement.
Jewelry and High-End Decorative Arts:
While less common due to cost and softness, it can be used for unique, avant-garde jewelry pieces or decorative inlays where its purity and luster are the main attractions.
