Copper Powder 99+%, Mesh 200

High-purity copper powder made via water atomization and hydrogen reduction. Features very fine, irregular particles and clusters with relatively lower density. Recommended for applications requiring high purity and conductivity, including diamond wheels, sintering, and chemical reactions. Note: Pure copper powders may not exhibit conductivity under low-voltage tests but will conduct when compacted or mixed with oils or resins.
