Copper Powder, Mesh 400

Highly pure >99% spherical copper powder made using inert gas atomization. Mesh 400 spherical copper produced from highly pure copper material, creating a fine, spherical powder suitable for advanced manufacturing applications. The powder has an HTS code of 7406.10.0000, NMFC code of 30743, and CAS number 7440-50-8. Particle size distribution includes 14.5% of particles below 10 microns, 20% below 50 microns, and 90% at 25.87 microns or smaller. Apparent density is approximately 4 g/cc. Suitable for electronics, injection molding, thermal management, EDM electrodes, thermal spray, and other applications requiring fine spherical powder.
