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.

Storage Note:
- The copper powder should store in a cool, ventilated warehouse. Away from fire and heart source .
- It should be stored apart from oxidant acids, halogen ,mixed reservoir of avoiding by all means.
- Equipped with corresponding varieties and number of fire equipment.
- Storage area should be equipped with the right material for leakage content.
