CNPC POWDER'S atomized copper powder is produced by the water atomization (pure copper powder) or gas atomized (spherical copper powder) methods. The copper powder comes in a pure fine powder form, including irregular and spherical shape. Cu content is 99.7% min. CNPC Copper powder properties of formability, inoxidizability, compressibility, sintering activity and well-developed surface are well-fitted in PM industry.

                                                      Copper Powder Production

The difference between Water Atomized Copper Powder and Gas atomized Copper Powder is their apparent density, particle shape, oxygen
content and color.

Atomized Copper Powder Storage Note:
  • The copper powder should stored in a cool, ventilated warehouse. Away from fire and other heart sources.
  • 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.
