Purity: 99.995%, Size : < 110 nm 

Silver Tin (Ag-Sn) Alloy Nanopowder is an advanced binary metallic system that integrates the noble characteristics of silver with the versatile metallurgical properties of tin to create a material with superior mechanical and chemical stability. At the nanoscale, this alloy overcomes the limitations of its individual components, offering enhanced wear resistance, high-temperature oxidation stability, and exceptional corrosion protection. The precise alloying process results in a material that exhibits unique wetting properties and lower melting points than pure silver, which is critical for precision bonding and high-reliability coatings. With its high purity and controlled particle size, this nanopowder provides a high-energy surface area that promotes excellent adhesion and catalytic efficiency, making it an indispensable resource for industries requiring durable, conductive, and environmentally resistant material solutions.

Technical Properties

Applications

• Electronics and Advanced Soldering: Ag-Sn alloy nanoparticles are a cornerstone in the development of lead-free soldering technologies and conductive adhesives. Their unique thermal profile allows for lower processing temperatures while maintaining high-strength mechanical bonds, making them ideal for micro-BGA packaging, flexible electronics, and high-density interconnects. The inclusion of tin enhances the wetting ability on various substrates, ensuring reliable electrical paths in miniaturized circuits.
• Surface Engineering and Coatings: These nanoparticles are extensively used in the production of wear-resistant and anti-corrosive coatings. When integrated into thin films, Ag-Sn alloys provide a protective barrier that resists environmental degradation and mechanical fatigue. This makes them highly suitable for aerospace components, automotive parts, and marine hardware where both aesthetic brilliance and functional durability are required.
• Biomedical and Dental Materials: In the medical field, Ag-Sn alloy nanopowders are utilized in dental amalgams and restorative materials due to their biocompatibility and excellent mechanical properties. Their antimicrobial nature, inherited from the silver content, combined with the structural stability of tin, makes them effective in medical device coatings and orthopedic implants, where they help prevent infection while supporting structural integrity.
• Energy Storage and Battery Technology: Ag-Sn alloys are explored as high-capacity anode materials for next-generation lithium-ion and sodium-ion batteries. The alloy structure helps mitigate the volume expansion issues typically associated with pure tin during charging cycles, leading to improved cycle life and better rate capability. This makes them valuable for developing more efficient energy storage devices and supercapacitors.
• Catalysis and Chemical Synthesis: The synergistic electronic effect between silver and tin atoms makes these nanopowders efficient catalysts for selective hydrogenation and oxygen reduction reactions. They are particularly valued in industrial green chemistry for their ability to increase reaction selectivity and reduce the need for harsh operating conditions, contributing to more sustainable chemical manufacturing processes.
• Specialized Lubricants and Additives: Due to their excellent load-bearing capacity and low friction coefficient, Ag-Sn nanoparticles serve as high-performance additives in lubricants and greases. They form a tribofilm on contact surfaces, significantly reducing friction and preventing surface galling in heavy-duty machinery and precision instruments.
