Spherical nickel powder: high-performance nickel-based powder
Nickel is a metallic material renowned for its excellent corrosion resistance, high‑temperature strength, and superior electrical and thermal conductivity, making it widely used in electronics, energy, chemical processing, and additive manufacturing. Spherical nickel powder is produced via vacuum atomization: high‑purity nickel ingots are melted and atomized under an inert gas atmosphere, followed by precise sieving to yield a premium powder with a sphericity of ≥95% and a tightly controlled particle size distribution. The product boasts a nickel content of ≥99.9%, an oxygen content of ≤0.2%, and impurity levels of Co ≤200 ppm, Fe ≤100 ppm, and Cu ≤100 ppm, meeting the stringent requirements of advanced applications. It exhibits outstanding flowability and a high tapped density, making it well suited for processes such as SLM 3D printing, metal injection molding (MIM), plasma spraying, conductive pastes, and battery materials. Particle sizes ranging from 15 to 53 μm are specifically engineered for additive manufacturing, enabling the fabrication of highly dense, complex nickel‑based alloy components; ultrafine powders in the −300 mesh/−400 mesh range are ideal for MLCC electrodes, conductive adhesives, and catalytic supports. Customizable particle sizes from 5 to 100 μm and nickel‑based alloy compositions—including Ni‑Cu, Ni‑Cr, Ni‑Co, and others—are available upon request.
