The application of silver coated copper powder is closely related to its powder properties and silver content. Silver coated copper powder with different shapes and silver content has different uses. Spherical silver coated copper powder has a wide particle size range, low loose density, good metallic luster, and a silver content generally between 3% and 20%. It is mainly used in non sintered products such as conductive coatings, electromagnetic shielding coatings, and low-temperature conductor slurries. Sintered medium temperature conductor slurry requires a spherical conductive phase, continuous and dense silver layer coating, and good oxidation resistance at a sintering temperature of 450-540 C. After sintering, the film layer maintains good conductivity and other properties.
Characteristics of spherical silver coated copper powder:
Spherical and quasi spherical silver coated copper powder is usually prepared by coating spherical copper powder; Good stability, dispersibility, and thermosetting properties
Product name: spherical Silver coated copper powder
Particle size: 1-3um, 5um, 10um
Silver content: 5%, 10%, 15%, 20%, 30%, etc
Morphology: spherical, flake, dendritic
1. The spherical silver copper conductive powder series products are used as fillers for conductive coatings, used for spraying on the surface of objects to conduct electricity. The role of shielding. For example, conductive paint (shielding paint), etc. It can also be used for screen printing silver paste products with a mesh size of 200.
2. Spherical silver coated copper powder is widely used as a filler for conductive inks and for screen printing, such as thin film switch paste. Inductive paste, solar electronic paste, PET paste, LED paste, and other conductive electronic paste. It has high antioxidant properties. Can be used for 325 mesh screen printing. Or used as a filling material for conductive rubber, suitable for adding to objects (or solid or fluid) for conductive connection, such as conductive adhesive, conductive cotton, conductive cloth, conductive pad, etc.
