Copper Powder 99.8%, Electronic Grade, Mesh 325

Electronic grade, high-purity copper powder made via water atomization and hydrogen reduction. Features ultra-fine, spheroidal particles with high conductivity and low density. Recommended for a variety of applications where conductivity is crucial, including thick and thin film pastes, capacitor chips, and thermal sprays. Note: Pure copper powders may not exhibit conductivity under low-voltage tests but will conduct when compacted or mixed with oils or resins.
