High-conductivity Filler Silver-Coated Copper Flake/Sphere particles

Product Performance and Characteristics:
The silver-coated copper powder is produced using advanced chemical plating technology imported from abroad, forming a silver coating of varying thicknesses on the surface of ultra-fine copper powder. It not only overcomes the oxidation susceptibility of copper powder but also solves the problems of high cost and migration tendency of silver powder. As a highly promising high-conductivity material, it is an ideal cost-effective conductive powder for replacing silver with copper.

Product Introduction

Silver-coated copper powder can be widely used in the fields of electrical conductivity and electromagnetic interference (EMI) shielding across various industries, including electronics, electromechanics, telecommunications, printing, aerospace, and military applications. Examples include computers, mobile phones, integrated circuits, various electrical appliances, electronic medical equipment, and electronic instruments, where it protects products from electromagnetic wave interference while reducing the harm caused by electromagnetic radiation to the human body. It is also used for conductive treatment of insulating materials such as adhesives and circuit boards, enabling insulating objects to achieve good electrical conductivity.
