Description
Copper (Cu) Nanopowder / Nanoparticles (99.9%, 40 nm, Metal Basis)
Our Copper (Cu) Nanopowder/Nanoparticles are produced using an Electrical Explosion Method combined with Laser Synthesis, ensuring highly pure (≥99.9%) and uniform spherical particles. With an average particle size (APS) of 40 nm and a specific surface area (SSA) of 45 m²/g, these nanoparticles provide exceptional electrical and thermal conductivity, making them ideal for advanced applications in electronics, catalysis, and lubrication.
The nanoparticles exhibit a dark brown appearance and maintain a consistent spherical morphology with 100% round shape formation. Their precise size distribution enhances their reactivity, surface area, and integration potential in high-performance industrial and scientific processes.
