Conductive Nickel Particles

Conductive nickel particles have excellent conductivity, with a resistivity as low as 6.84 × 10 ⁻⁸Ω· m, and can be used as a key component of conductive pathways. The particle morphology mainly includes spherical, sheet-like, and fibrous shapes, among which spherical nickel powder has good flowability and is suitable for scenarios such as conductive adhesives and 3D printing; Flake nickel powder exhibits superior coverage and reflection loss in electromagnetic shielding coatings due to its larger aspect ratio. The product purity can reach over 99.9%, with a common particle size range covering nanometer to micrometer (50 nm-50 μ m), and can be customized according to demand.

 

 

Main application areas

• Electronic conductive adhesive and coating: widely used as conductive fillers in integrated circuit packaging, PCB board printing, keyboard contacts, etc., providing stable and reliable conductive connections.
• Electromagnetic shielding (EMI/RFI) materials: Prepare lightweight, high-strength polymer based shielding coatings that effectively shield high-frequency electromagnetic interference and meet the compliance requirements of 5G communication and electronic devices.
• Electrode materials and new energy batteries: used as conductive reinforcement layers for electrodes in nickel hydrogen batteries, supercapacitors, etc., to improve rate performance and cycle life.
• Ceramic capacitors and MLCC: As internal electrode materials, continuous metal phases are formed after high-temperature sintering, achieving miniaturization and high capacitance density.

Compared to precious metal conductive fillers such as silver and copper, conductive nickel particles have outstanding cost-effectiveness and a more advantageous price per unit of conductivity. Its surface can undergo antioxidant treatment (such as passivation and coating), significantly improving its long-term stability in high temperature and high humidity environments. In addition, nickel particles have ferromagnetism and can also serve as magnetic functional components, achieving integrated design of conductivity and magnetism.

We strictly implement the ISO 9001 quality management system, and provide key parameters such as particle size testing report (laser particle size analyzer), specific surface area (BET method), and tap density for each batch of products. For special application requirements, we support surface modification (such as silane coupling agent treatment) and customized particle size/morphology development. We provide full process technical services from selection guidance, sample testing to bulk supply, ensuring that customers achieve the best application results in the research and production of conductive pastes, composite materials, and other materials.
