Silver coated aluminum powder widely used in conductive and shielding materials

Silver foil aluminum powderIt uses chemical plating technology to form silver coatings of different thicknesses on the surface of aluminum powder through specific forming and surface treatment processes. It has good conductivity of pure silver and other metals, as well as advantages such as low density, low cost, low oil absorption, narrow distribution, and easy dispersion. It can be widely used as a filler for conductive and shielding materials. It is a highly conductive filler with great development prospects.

The main process of silver coated aluminum powder is: aluminum powder coarsening water washing sensitization activation water washing silver plating water washing drying. Specifically, the aluminum powder is first corroded and coarsened with an alkaline solution, deionized water washed, quickly added to the sensitization and activation solution and continuously stirred. After thorough cleaning with deionized water, it is placed in the silver plating solution. Finally, the powder is removed, cleaned, dried, and its performance is observed and tested.

useSilver foil covered with aluminum powderThe prepared material maintains the advantages of aluminum powder itself, while also improving its conductivity and oxidation resistance, and reducing costs. Silver plated aluminum powder, as a functional conductive filler, can be added to coatings, adhesives, inks, plastics, rubber to make conductive, electromagnetic shielding, anti-static and other products. It is widely used in the fields of conductivity, electromagnetic shielding, anti-static in electronics, electromechanical, communication, printing, aerospace and other sectors.
