SAT NANO flake Silver coated copper powder has a range of potential uses. SThe flake silver coated copper powder has good conductivity, high chemical stability, difficulty in oxidation, and low price. Flake Silver coated copper powder is available for 1-3um, 5um, 10um, high purity 99.9%, Morphology: spherical, flake , dendritic. Please feel free to check the specification.
The conductivity of copper is similar to that of silver, and it is cheap, making it an ideal substitute material for silver. Due to the relatively active chemical properties and easy oxidation of copper powder, it is not conducive to industrial application. Using copper powder silver plating to solve this problem can achieve good results.
Flake silver coated copper powder is usually prepared by ball milling and coating of flaky copper powder; Good stability, good antioxidant performance, and good two-dimensional conductivity.
Silver plating on flake copper powder is difficult, and SAT NANO has studied the preparation process and antioxidant performance of silver plating on copper powder. The experimental results show that after special treatment on the surface of copper powder, dotted silver particles are generated, and then the silver particles grow up, incompletely coating the surface of copper powder. The excess silver ions in the solution, under the action of reducing agents, further grow the surface silver layer, resulting in fully coated copper powder. Through X-ray diffraction analysis, no oxide was found on the surface of the silver plated layer of the flake copper powder, and the surface structure of the obtained powder was dense. The silver plated layer of copper powder has good resistance to high-temperature oxidation.

At present, the preparation process of copper powder silver plating is complex and the coverage rate is low. To address the above issues, SAT NANO has developed flake silver coated copper powder with standardized preparation process, controllable process, high coverage rate, and good application value. Currently, the flake copper powder prepared by this process is widely used in fields such as electromagnetic shielding and conductive adhesives for silver plating.
Flake Silver coated copper powder, as a good high conductivity filler, can be added to coatings (paint), adhesives (adhesives), inks, polymer slurries, plastics, rubber, etc. It can be made into various conductive and electromagnetic shielding products, and is widely used in various industrial sectors such as electronics, electromechanical, communication, printing, aerospace, weapons, and other conductive and electromagnetic shielding fields. Conductive and electromagnetic shielding of electronic, electrical, and communication products such as computers, mobile phones, electronic medical equipment, electronic instruments and meters.
