CNPC POWDER electrolytic copper powder is produced from the mixture of sulfuric acid and copper sulfate as electrolyte with electrify. As raw materials, the materials melt into liquid after high heating and become tiny particles after water or gas blowing. Electrolytic copper has a high purity of Cu content 99.7%.The powder has low apparent destiny and a dendritic powder shape.

Electrolytic Copper Powder has the properties of well electrical and thermal conductivities.

Electrolytic Copper Powder Production Process

Step2: Electrolytic

Step3: Copper powder

Step4: Washing

Step5: Centrifugal

Step6: Dry


Step8: Inspection
