Advanced Silver-Coated Powders from Toyo JWX Powder: Silver-Coated Copper and Silver-Coated Silica for High-Performance Applications
Toyo JWX Powder, a leading manufacturer of advanced metal powders based in Hunan, China, offers a specialized silver-coated product series designed to meet the demanding requirements of modern electronics and functional materials. Among these, silver-coated copper (Ag-Cu) and silver-coated silica (Ag-SiO₂) powders stand out for their exceptional performance and reliability.
Silver-coated copper powder combines the high electrical conductivity of silver with the cost-effectiveness of copper. Available in both spherical (e.g., TFM-CO2P, TFM-CO5P) and flake-shaped (e.g., TFM-CO5F, TFM-C15F) morphologies, it features silver content ranging from 10% to 20%. Key advantages include excellent electrical conductivity, superior thermal stability, and high cost-performance ratio. These properties make it ideal for applications such as printed circuit boards (PCBs), conductive adhesives, EMI shielding, touch screen sensors, conductive tapes, and conductive inks.
Silver-coated silica powder, on the other hand, leverages the insulating nature of silica while enhancing surface functionality through a uniform silver layer. Products like TFM-S02P and TFM-S05P contain 30% silver and offer fine particle size control (D50: 2.0–4.0 μm). This material delivers outstanding chemical stability, good thermal stability, strong conductivity, and excellent value—a rare combination for non-metallic core fillers. It is widely used in conductive adhesives, PCBs, EMI shielding, and flexible electronic components where controlled conductivity and reduced density are critical.
Both product lines are developed under the technical collaboration of Toyo Aluminium K.K. Group and manufactured by Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. , ensuring stringent quality control and consistent performance.
