(1) Product performance and characteristics:
Silver coated copper powder introduces advanced chemical plating technology from abroad, selects German molding and surface treatment equipment, and forms silver coatings of different thicknesses on the surface of ultrafine copper powder; Compared with similar products, it has good antioxidant performance, good conductivity, low resistivity, high dispersibility, and high stability; It not only overcomes the defects of easy oxidation of copper powder, but also solves the problems of high price and easy migration of silver powder. It is a highly conductive material with great development prospects, and is an ideal conductive powder with high cost-effectiveness that replaces silver with copper.
This product adopts an environmentally friendly cyanide free chemical plating process to develop a silver copper powder with good conductivity. The volume resistivity of the powder is less than 2 × 10-3 Ω. cm, a conductive coating made from this powder as a filler, with high conductivity (volume resistivity of 5 when the weight ratio of conductive filler to resin is 75:25) × 10-3 Ω. cm), strong migration resistance (nearly 100 times higher than ordinary silver powder conductive coatings), stable conductivity (after 1000 hours of 100% humidity test at 60 ℃, the volume resistivity increase is less than 20%).
The Flaky plated Silver Copper powder produced by our company has a silver content between 5% and 30%. Customers can choose according to their own needs or order any silver content of Flaky plated Silver Copper powder.
(2) Purpose:
Silver coated copper powder can be widely used in conductive adhesives, conductive coatings, polymer slurries, and various microelectronic technology fields that require conductivity and static electricity, as well as industries such as surface metallization treatment of non-conductive substances. It is a new type of conductive composite powder.
Widely used in conductive and electromagnetic shielding fields in various industries such as electronics, electromechanical, communication, printing, aerospace, military, etc. For example, computers, mobile devices, integrated circuits, various electrical appliances, electronic medical equipment, electronic instruments and meters, etc., ensure that products are not affected by electromagnetic waves, while reducing the harm caused by electromagnetic radiation to the human body. Additionally, conductive treatment of insulators such as colloids and circuit boards ensures that insulated materials have good conductivity.
